    Sanyo dc j3k

    Hi there I've just bought a SANYO DC J3K stereo receiver amp off eBay as i primarily liked the look and the price was right. I have a Marantz 1550 that i'm (slowly) restoring, and I needed something of approximately the same vintage to complement my set-up that wasn't going to cost a fortune. Its from a seller I've used before so I'm hopeful when they say its been tested as fully working. Depending on what I get in the post though I may need to tinker with it and so I went looking for a service manual, but no dice.

    I know this model was was originally sold as part of a music system comprising of a turntable and speakers and I've located an owners manual, but that really is not much more than a, "here's where stuff gets plugged in..." type of guide, it has no specs regarding power output, frequency response etc., but it does have a circuit schematic?

    Any additional intel on this model would be great.

    Here's a picture I located on hifiengine of the same model (no official entry in their DB). I've contacted the poster of that image, but its from 8 years ago, so i'm not super hopeful for an answer.

    Best Sanyo made in the 70's was the JCX 2900K. Easily bests everything made by the big dogs (Pioneer/Marantz etc) during that era. You can get this TOTL Receiver for 30-50% of what the Best Pioneer/Marantz receivers go for. $500 is about the average price. If that's too rich for you go for the 2600K Model which is around $200.
    Amps: First Watt SIT-3, Pass XA25, Valvet E2 SE, LTA Ultralinear, ARC 150M, First Watt SIT-1 Mono's, ARC Ref75SE, Luxman M900U, Pass XA30.5, Decware Zen TorII MK4, Line Magnetic 845 Premium, Raven Reflection MK2

    Pre-Amps: Luxman 900U, ARC MP-1 Multi-Channel, Conrad Johnson Met-1 Multi-Channel

    Disc Spinners: Luxman D-08U, Ayre DX5, Oppo 105/205

    Speakers: Joseph Audio Pearl 3, Dynaudio Special 40, Falcon LS 3/5A, Klipsch Cornwall IV, Harbeth SHL5+, Omega Compact 8, Triangle Comete EZ, Monitor Audio Gold 200, JBL 590, Audio Solutions Figaro M

    quick update, receiver arrived in very smart condition, just a couple of bulbs to replace (done). It's got 4 channel matrix stereo sound. I managed to measure 3w per channel output. It was at first a little disheartening as i was hoping for at least 10w per channel, i had no specs to manage my expectations. However I was pleasantly surprised that's its able to power my 40w 3 way floor speakers to an acceptable level for my small study. So given this is meant to be just my stand in receiver it will absolutely do for now. BTW once I had it open it appears to be very similar inside to the contemporary dxc units of the same era, so if i need to go tinkering further I think I can find enough material from those more well known units to help me. Going forwards I may try and locate some slightly better matched speakers, i'm not sure yet, it really depends on how long the Marantz is out of commission, but overall very happy with this little unit.
