Why don't you contact John Weeks at :
John Weeks — Silver Pioneer Stereo Collection.
He might have some addresses.
In memory of my brother who recently passed away at the rather young age of 55, I am now working on rebuilding his stereo that he had assemblied while stationed in Germany back in 1976. While I have part of it, the core I do not have at this moment. It means a lot to me only because for hours we would listen and tinker. This time with him had such an impact on me that it led me to my eventual career.
I am now working on finding and getting a Pioneer SPEC-1 preamp and a SPEC-4 amp, while he also had a Nakamichi 610b preamp, that one may come latter in the process.
Any ideas or locations of dealers moving vintage gear in good shape would be great!
Thank you guys!
