Vintage Stereo Receivers ~ Tuners ~ Amps

Kenwood KR-7050

Kenwood KR-7050 (1980) 80W x 2 $285

This is a pristine condition (near mint) Kenwood masterpiece...a "High Speed DC with zero switching" receiver with a ridiculously low total harmonic distortion and class-leading frequency response.  This guy also has four gigantic meters that splash across the front silver face.  Rated at a conservative 80 watts per channel into 8 ohms (and an astounding 160 watts per channel in 4 ohms).
Here are some of the features:
Two tape monitors, one phono and aux inputs, bass and treble turnover controls, separate mid control, DC Coupled, high filter, tone on/defeat, FM 25us on/off, FM muting on/off, If Band narrow/wide. Also features a mic input, and those four big meters are tuning and signal meters, and both right and left channel output power meters. 
As we've said before, we hesitate to use the word "mint" (because it's over used) but this one is very close to mint.  And, of course, the beautiful walnut case is flawless as well.

About Kenwood (Trio)...

Established in 1946 as the Kasuga Radio Co. Ltd. in Komagane City, Japan, in 1960 the company was renamed Trio Corporation. In 1963 the first overseas office was founded in Los Angeles.

In the early 1960s, Trio's products were rebranded by the Lafayette Radio Co with a focus on CB radio.

An importer of Japanese-made electronics Radio Shack (Realistic, Tandy Corp) was A&A Trading Co., and a bilingual Japanese-speaking manager from there established a company that would be the exclusive importer of Trio products.

The name Kenwood was invented by Kasuga as being the combination of "Ken", a name common to Japan and North America that had been tested and proven acceptable to American consumers in the name of Kenmore appliance (Sears) \, and "Wood", referring to the durable substance as well as suggesting a relation to Hollywood.  The brand recognition of Kenwood eventually surpassed that of Trio's, and in 1986 Trio bought Kenwood and renamed itself Kenwood.  Eventually, Kenwood merged with JVC in 2008 as JVC/Kenwood.



Concept 3.5

Concept 3.5 ('75-'78) 35W x 2  $200

We love to find excellent, hard to find vintage gear...especially when they are as nice as this 3.5 which is in near mint condition. Very conservatively rated at 35 watts per channel, this rare Concept 3.5 is a heavy duty, well designed, stereo receiver known for it great bass control, sound stage presentation and a very accurate tuner, The direct-coupled power amplifier section uses high gain voltage amplification with rugged output transistors for a stabilized, high speed configuration. A large toroidal power transformer supplies enough power for the most demanding musical peaks.  Unlike most comparable receivers in this class, the 3.5 was designed with internals that were ahead of their time...just like all the Concept receivers, regardless of size and power.  As with all the Concept receivers, this too has one of their trademark design elements...a nice rosewood veneer case.

About Concept...
Recognized universally as some of the very best stereo receivers ever made, the Concept receivers circuitry was designed in-house, by Dick Schramm, at Pacific Stereo (late 70's California). Tom Ishimoto, former product development manager of Marantz, also had a hand in building some of the Concept line at NEC of Japan. The bulk of the manufacturing was done by TCE, an electronics manufacturing division of Tandy Corp. (Tandy was the parent company of U.S. electronics retail chain Radio Shack). A lot of effort was made in upgrading the Concept design capabilities, and TCE's production techniques at the time were described as "terrific". Several other manufacturers were considered for the Concept receivers, but, as far as Schram was concerned, TCE was by far the best. They had gifted engineers who were excited to work on some REAL hi-fidelity audio products and became very loyal to him during the entire process. The Concept credo was "better quality parts, operated with more margin of safety, superior circuits and no shortcuts" - that's why they last so long and still sound as good today.

More about Pacific Stereo (and Concept...)

The Concept line of stereo receivers were offered by Pacific Stereo as their top tier house brands. (in order, top to bottom: Concept, Reference by Quadraflex, Quadraflex and TransAudio) The top of the line was the Concept 16.5 (165 watts per channel, considered by many to be the best stereo receiver ever made!).  Basically, when a customer went into a Pacific Stereo store looking for Pioneer, Sansui, Kenwood, etc, the salesman would steer them toward one of the "house" brands, the best of which were the Concepts.  Normally you might think that the house brand would be some cheaply made unit designed for maximum profit to the retailer. But, in this case, the Concepts (and secondarily, the Reference series) were very well built and high performing receivers.  Especially the Reference 650FETR which was Richard Schram's baby all the way, a very fine stereo receiver that deserves to be in any serious audiophile's collection.


Rotel RX-603

Rotel RX-603 (1977) 45W x 2  $165

Hard to find and in near mint condition, this solid Rotel RX-603 is a massive block of well-designed aluminum, packed with superior components that​ rarely need servicing.  The distinctive front faceplate has the signature Rotel FM window shape that sets them apart from all other receivers of the 70's.  Rated at a minimum 45 watts per channel, it sounds like a lot more. Real aluminum knobs, large rectangular push buttons, rack handles and a pleasing soft yellow dial light are just a few features of this very excellent vintage piece.

About Rotel... Rotel is a family-owned Japanese manufacturer of high end audio and video equipment. The company was established in 1961. In the early 1980s Rotel joined the B&W Group forming a strategic alliance with Bowers and Wilkins and later adding Classé Audio.


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

Sanyo JCX-2400K (1978) 55W x 2 $190 

Near mint condition, this powerful and well built Sanyo JCX-2400K is one of those rare combinations of beauty and the beast. Beauty in its stunning silver face design and lots of punch because it's packed with Sanyo's own proprietary components.  The JCX-2400K units are getting harder to find, especially in such fine condition as this one.  A little research will prove the value and yield many excellent rave reviews from those that know a high quality vintage stereo receiver when they find one.

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  and PLUS series of receivers are 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.
