Vintage Stereo Receivers ~ Tuners ~ Amps

Sony STR-V6

Sony STR-V6 (1978) 115W x 2  $475

Th​is​​ rarely seen true​ ​monster Sony STR-V​6 is ​second only to the top of the line STR-V7.  It was introduced around 1978 and has the classic 70's Sony styling with its low key sophistication and lack of over​-​the​-​top eye candy.  Built like "tanks" (as the saying goes), these were made to last a lifetime​, much r​ather classy than brassy ​.  Selling abundantly in Europe, not as much in the US and not at all in Japan - this first "STR-V" series was export-only.
​The green ​lamps ​glow ​across​ ​the entire front AM/FM panel and three analog meters.  The brushed aluminum knobs make an upscale and sleek impression. ​T​he build quality and performance is very, very good and easily compares to ​some of those more well known and coveted brands.  The Sony STR-V​6​produces​ a conservative​ ​11​5 watts per channel into 8 ohms​. The green glow and chrome frames are carefully balanced with the different finish textures​, real ​class.
The interior design is very impressive with its​​​ huge ​toroidal power transformer​, 15,000uf Nippon filter caps, 5 gang FM tuner, inputs for two turntables, tape, aux, etc. 
At 41 lbs, it's solid heavy and has beautiful real wood side panels with walnut veneer.  Like we said, it's big... 21" wide, 18" deep and 8" high.
​All meters working, FM bias adjustment done.  All inputs/outputs, knobs, switches, etc function correctly and the cosmetic condition is near mint.


Optonica SA-5406

Optonica SA-5406 (1980) 65W x 2  $270

By now, if you've seen our gear, you already know that Optonica is one of Cherry Vintage Audio's featured vintage brands.  No longer "under the radar", the Optonica equipment is just so damn nice! 
Here we have another of the rare, very excellent and very good looking SA-5406 vintage receivers from Optonica.  
Rated at a very conservative 65 watts per channel, the SA-5406 was third from the top of the line in 1980.  These have reached the status level of higher end vintage units that are being sought after by audiophiles.  The quality of the Optonicas are right up there with the best of Pioneer, Sansui, etc.  The black faceplate, trademark teardrop-shaped machined black aluminum knobs with silver trim are all unique to the Optonica SA series.  The rosewood veneer case is also common to this series, it's very attractive.
One of the many unique Optonica features was the addition of an "Air Check" button on the front panel (the "air check" calibration tone of approximately 404.8hz for your recording levels if you want to record AM/FM broadcasts and allows you to set your max levels instantly.)

Optonica SA-5605

Optonica SA-5605 (1980) 85W x 2 $390 

This is one very rare and powerful beauty from Optonica.  
Conservatively rated at 85 watts per channel, the amplifier section is "OCL Class A" (output capacitor less) and actually produces closer to 97 watts per channel (RMS) @ 8 ohms.  The SA-5605 is edging into the monster class...both physically and internally.  
At 22" wide, 7" high and about 37 lbs, it's definitely huge, impressive and powerful, to say the least.  Another great spec is it's frequency response: 15Hz to 50kHz!

The four meters have a nice white glow as does the wide linear FM scale.  This has the unique feature that allows you to shut off the FM tuner while using different inputs/outputs.  This reduces any chance of distortion or interference from the tuner section.  Inputs/outputs for two turntables and three pairs of speakers along with the numerous switches, knobs and controls assure this giant beauty as easily being the strong anchor for just about any type of sound system you can think of.  
As mentioned before, these are very rare...The rosewood veneer case and the anodized, black aluminum, tear-drop, polished silver tips on the knobs and switches are an Optonica trademark design. 

About OPTONICA (Sharp Electronics of Japan)...
The Optonica brand was created and first launched by Sharp in 1976 as a separate high-end brand to compete directly with Pioneer, Technics (Panasonic), Fisher, Marantz, Nakamichi, Sansui, Kenwood and Sony.  Sharp Electronics Corporation of Japan was founded in 1912 and takes its name from one of its founder’s first invention, the "Ever-Sharp" mechanical pencil. Obviously, they also designed and sold much more over the years.  By the mid-70's their electronic equipment (mostly gadget oriented items sold in catalogs and department stores) was well situated in the USA.  Major decisions were made to move into the select high-end stereo component market.  They absolutely hit a home run with their Optonica lineup. Unique, powerful and definitely well built, they are now very well known and commanding prices approaching the better Marantz and Pioneer units.


Zenith MC-7051

Zenith MC-7051 (1981) 40W x 2 $160

Zenith?  The grand old American company that made TV sets?  Yep...however, the MC-7051 is not your grandpa's Zenith gear.  One of the most sought after vintage receivers, it's no longer a longer "under the radar" either.  Extremely well made with components that rival the best of "the other guys", this good looking receiver has a very light gold tint on the faceplate and a very clean, straightforward design up front.  It's heavy too, with a strong transformer and power supply that was specifically designed by...(are you ready for this?)...*Samsung in Korea.  It was a secret back when it was being designed and when it was released, it didn't sell very well. Simply put, Zenith did have a great unit but it was a little late in the game.  Besides, most people associated Zenith with televisions and it didn't seem plausible they could build a receiver that could compete with the famous names. they are rare and sought after.  There's a reason why...

NOTE: The vintage Samsung 3390 vintage receiver has an almost identical interior build as the Zenith MC-7051.  They felt since they designed one for Zenith (and it was really good!) wny not make one for themselves?  When Zenith found out, they threatened to sue Samsung so...that was the end of the Samsung 3390.

HH Scott 375R

HH Scott 375R ('81-'83) 65W x 2 $180

Built to compete with Sansui, Pioneer and the other well known names, HH Scott's reputation was well established after the 70's.  It's common fact that Scott didn't spend a ton of money on advertising, relying instead on high quality components and word of mouth. The 375R was Scott's mid size entry in the analog/digital market that was taking over the market in the early 80's. The FM digital LED readout is sometimes a little erratic but since this also has the perfectly working analog tuning dial as well, it does not affect performance at all.  The front silver face with fluorescent blue LEDs is quite fancy and adds a touch of vintage cool.  Powerful, heavy and, of course, very well built, Scott added phono inputs for both MM and MC, a truly nice touch.  Three level controls for low, mid and highs (another nice touch) and nice walnut side panels, the 375R is a premium receiver getting harder to find in such great condition.

About H.H. Scott...

Hermon Hosmer Scott held many patents and was instrumental in the birth and development of high fidelity sound equipment.  HH Scott, the famous name by which he and his firm were so widely known, became one of the top two respected names in consumer high fidelity (and later stereo), the other also bearing its founder's name, the very famous Fisher Radio.  As mentioned above in description of the 375R, Scott was one of several top notch brands that built seriously good equipment but spent very little money advertising their gear. Consequently, they didn't sell in large numbers (compared to Pioneer, Sony, etc that spent many millions more in advertising) but they did sell excellent equipment.  Scott is a brand that's a little harder to come by but well worth the time and effort to seek them out.


Pioneer SX-650

Pioneer SX-650 ('76-'78) 35W x 2  $150
(on hold for customer until 10/20)

This particular Pioneer is exceptionally clean.  One of the classic mid-range receivers offered by Pioneer in the mid 70's was this Pioneer SX-650. As you can see it has the classic silver face styling of Pioneer's SX series which, when coupled with the walnut veneer case, makes for a popular and stylish looking receiver.  The SX-650 was produced from 1976-1977 and originally sold for around $300.00.  The SX-650 puts out a conservative 35 watts per channel (8 ohms RMS) and was designed and marketed for those with an average sized listening room and who wanted good value for their money. The 650 didn't have too many frills but what it did, it did well.  

About Pioneer...

Not much needs to be said about Pioneer other then the simple fact that the name is known worldwide for above average quality and excellence in high fidelity component design.  They were the unchallenged leader in stereo advertising and marketing in the 70's.  Back in the day, Pioneer made it clear that if you didn't have a Pioneer stereo system in your house (or college dorm) you just didn't have the right stuff.


Toshiba SA-420

Toshiba SA-420 (1977) 30W x 2 $165

Another great build by Toshiba, the SA-420 is very well built and heavy receiver. Above average switches and pots. All discrete internal components - good size transformer...It's one of the physically largest, medium powered receivers we've seen.  It has clean lines with an elegant knob design and a mellow, warm glow when lit up.  The split walnut veneer case design is exclusively from Toshiba that gives it a unique look in comparison to other units from the era.  Specs vary online but it matters not, the SA-420 easily drives two pairs of efficient speaker systems.  No doubt one of the easiest to service, the interior build is uncluttered and laid out very nice.  

About Toshiba...

Today, most recognize the name Toshiba primarily because of its monster class SA-7150 with its massive power at 150 watts per channel.  But, back in the early 70s, when HiFi dealers took on the Toshiba audio product lines, the salesmen considered them a second-level product line to the Marantz, Pioneer, Sony , etc. However, as time went on and technicians began to open them to see inside, they spread the word and slowly, people started to change their minds. 
At the time, most Toshiba, Sanyo and other similar brands were associated with clock radios, and similar little devices that showed up in various stores that normally didn't sell hifi gear.
For the dealer, Toshiba was agressively priced so that there was better margin in their products, which translated to higher profits. This was because Toshiba didn't advertise or get product reviews from the audio magazines. Today, this explains why Toshiba is less known in general about the very good quality in their stereo equipment.
In fact, their gear was quite good, performed as good as the big-name gear and still does today - when you can find them. Because of their low key marketing stance, it's doubtful their sales volumes were anywhere near those of Sony, Pioneer, etc.


Hitachi SR-804

Hitachi SR-804 (1978) 50W x 2  $220

Promoted as "The world's most powerful 50 watt receiver", the SR-804 was also Hitachi's most powerful receiver in 1978. It's a beautiful, very well made,classic vintage receiver, produced in Japan.
With the beautiful nickname "Dynaharmony" (Class G) it's rated at a conservative 50 watts per channel (nominal power at 8 ohms). The legendary Class G circuit instantly provides up to 100 watts per channel to handle momentary peaks in certain musical crescendos.
Along with its four beautiful analog meters spanning across the front, the FM glass is also continuously illuminated.   
Visually, the Hitachi SR-804 makes a solid impression. It features a hardwood case with sculpted vent slots (not metal) and a gorgeous front panel made of thick satin finish aluminum. All the polished edge knobs and switches are also made of aluminum and have a very good feel and wonderful pressure points.

About Hitachi...
Class G is just one example of Hitachi's leadership in vintage audio technology. Power MOS FET amplifiers, R&P 3-head system cassette decks, Uni-torque turntable motors and gathered-edge metal cone speakers are just some of the others. There's a lot more.  Hitachi of Japan was one of the companies that made their own filter caps, transformers,  They also supplied many other famous names with Hitachi-made components (like Pioneer, Sony, even Marantz used Hitachi parts.)


Technics SA-200

Technics SA-200 ('78-'79) 25W x 2  $135

The smaller sibling of the late 70's SA Series from Technics, the SA-200 still has the power and looks of this fine family of receivers.  All new lamps cast a soft warm glow across the silver face. The specs on this receiver are outstanding, so don't let the minimum 25 watts per channel mislead you;  It can drive two pairs of efficient speakers and handle all the requirements needed to fill a small room or office with fine quality sound.  The walnut veneer case adds the final touch to this beauty. 

Technics SA-5370

Technics SA-5370 (1977) 48W x 2 $185

The Technics SA-5370, at 48 watts per channel, was right in the middle of the pack in the SA series in the late 70's.  Beautiful sculpted walnut case, twin meters, light blue FM glass that turns a bright white when powered on...easily drives two pairs of speakers plus aux, phono, tape inputs.  This was the last of the brushed aluminum face from Technics because, in 1978 they went to the smooth aluminum.  Also, the ribbed aluminum knobs and switches are a touch of class. Easy to service (if ever needed) and very reliable, great build, very popular vintage receiver.


Founded in the 1920's, the huge Japanese conglomerate Matsushita had interests in many electronics companies.  The most well known would be Technics and Panasonic. Technics was introduced as a brand name for premium loudspeakers marketed domestically by Matsushita in 1965.  Eventually, Technics became a premium brand bringing classics like the SL-1200mkii turntable and the absolute monster receiver at the top of the list: Technics SA-1000 (330 watts per channel.


Sanyo Plus 75

Sanyo Plus 75 (1979) 75W x 2  $325

Very rare and very powerful (with a very recent partial recap and new modules July 2017), this beauty is near mint condition inside and out.
This very nice Sanyo Plus 75 features (minimum) 75 watts per channel @ 8 ohms, 20hz to 20khz both channels driven @<0.03% THD. (Sanyo produced some higher end product in the late 70's, and the Plus series was designed to compete in the higher end market.)    Besides the digital AND analog tuning up front, it has three selectable roll-off frequencies for bass, treble and mid range tone control...tone defeat, 20db muting, MM/MC phono, and the tuner features a really neat digital frequency readout that moves up and down the tuning dial as the receiver is tuned. The beautiful real walnut side panels and the walnut veneer-on-metal top look great on this receiver.  
There are a LOT of other features, suffice to say this is a fine sounding receiver, and the tuning section performs very well.  All in all, a very fine example and beautiful piece of audio history. The Sanyo Plus series were Sanyo's top of the line units and are comparable to (if not better than) the well known and very popular Sansui "G" series of the late 70's early 80's....

Sanyo JCX-2400K (stock photo)

Sanyo JCX-2400K (1978) 55W x 2  $190

We've had a few of these amazing receivers over the years and are always grateful to have another to share with those looking for an excellent​ anchor for their vintage stereo system.  Noted for their units being built entirely "in house", Sanyo never skimped on the quality of their JCX series.  This one is a heavy unit with oversized heat sinks and a generous power supply.  Rated at a minimum 55 watts per channel, it seems to have way more power and can drive most any speaker systems with ease.  And, it's beautiful!  The silver face front end design is just gorgeous to look at; aluminum knobs with Sanyo's trademark "split knob" accents, attractive meters and distinctive walnut case with aluminum edges define the high quality of the JCX-2400K.

About Sanyo...

Sanyo Electric Co., Ltd. was a Japanese major electronics company and formerly a member of the Fortune Global 500.  They were one of the few electronics companies (like Hitachi) that made most of their own high fidelity components in-house using their own parts.  They also supplied some of the other big names like Pioneer, Sansui, etc. with Sanyo built parts and components. Their late 70's JCX series of receivers were very well known and in high demand by audiophiles.  At one point in their history, they had over 230 subsidiaries and affiliates.  Sanyo was eventually bought by Panasonic in 2009.

About Realistic/Optimus/Radio Shack/Tandy Corp...

Realistic branded vintage stereo gear is all over the place.  Some of it is right up there in quality with the best of Pioneer, Sansui, etc.  Also, some of it is just...ok.   Their best era was during the 70's when they successfully competed head-to-head with all the big names in high fidelity.  They sourced practically all their products from Japan and sometimes had the exact same components inside their gear as the competition but at a much lower price.
