    I've received a couple requests for the 400+ Schematics that I scanned and saved a while back. I don't have the amp anymore.

    I would like to thank you as well, OP. I will pass these along to the proper authorities. My 400+ is at the tech's as we speak getting a full array of JJ 6L6GC Powers, TungSol Pre's, and a dual pot bias. Oh man, I can't wait to get her back.
