    Is there a known good source for SPEC parts?

    Hi, Recently bought a Spec-1 that was on a tech's bench used as a switching device (as I understand). This unit appears to have been a donor unit used to keep other units in service as various parts are missing. The unit is operational and rather well. Great!!! But I want to restore it as...

    How to wire a pioneer spec 1?

    Hello everyone. Recently I came across a seller that is offering a pioneer spec 1 for a fair price in an ideal condition. I love the piece, but researching a bit around I found that it needs a spec 2 or 4, or an equipment with pre out/in, in order to work. I looked at My equipment and didn't...

    Pioneer Spec Rack Build

    After years of scrounging around craigslist for values on Pioneer Spec equipment, I finally have enough bits to put together a proper looking rack. Only to learn that the Pioneer Spec racks (JA-R2S) are unobtainium. I pretty much saw that coming. So I developed a plan to make one out of...

    Building A Rack

    Greetings! I've got a robust Pioneer Spec system that I'd love to throw into an ACTUAL rack. However finding a Pioneer Spec Rack is impossible, or insanely expensive, and while I love the looks of the racks at AudioRax.com you're pushing $800-900 for a 24U unit. Has anyone built their own rack...

    Replacement Pioneer Feet

    I have a Spec 1 and Spec 2 that need new feet. Can anyone recommend some replacements? I don't plan on rack mounting them and some feet would be helpful. (And what size and length screws?)

    Pioneer C-77 and M-77 voltage

    Hi everyone, I bought a Pioneer C-77 and m-77 yesterday in great shape. I have been jonesing for a spec system for a while now. So, my system has begun. However, I got it home and realized there was a possibility that I needed to change something or verify if the unit has been adapted to run on...

    3rd System, A Year Later.

    Still enjoying this grand setup that I acquired last year. One of my goals in Pioneer collecting was to have the opportunity to own both a SPEC-2 & SPEC-4 setup at the same time, and that goal has been met! This year I added the Pioneer store display lighted sign & Monitor 10 headphones to round...

    An amplifier performance testing sheet

    I just figured I'd share the Excel sheet that I use for testing amplifiers in my shop. It's basically a suite of 17 tests to figure out if an amplifier is working properly/performing in spec. Most of the tests assume that you have some form of distortion meter, like a HP 339A or a low-noise...

    Pioneer SPEC-1 Missing Loudness Function

    I am considering the purchase of a Pioneer SPEC-1 preamp. I have discovered that one of my favorite preamp features, Loudness, is not included in the SPEC-1's functionality. Does anybody know of a work around? Maybe Loudness can be simulated with EQ or maybe a circuit modification can be...

    2 Pioneer Spec 2

    OK I am acquiring vintage SS amps when and where I can. There is a person not too far away who has 2 Pioneer Spec 2's and 2 Pioneer Spec 4's he wanted to pass along. I told him I would take both the Spec 2's. I am sure there are many that are very familiar with the Spec 2. I am very green when...

    Another MC225 rebuild-voltage tolerance

    I am a new member who joined to because my old mc225 died and I decided to fix it myself. I am a genetic engineer so am comfortable with technology but have no electronics training. The sudden death of my mc225 turned out to be a shorted output transformer--it is now being rewound by doc...
