RE: Dynaco 400 amplifier problems,

Posted by GP49 on February 22, 2012 at 16:16:38:
Could be one of those "whatever we have in the parts warehouse" kind of things that Dynaco was famous for. I've had three of those, too. Two of them, I fixed for "owners" who never reclaimed them. After looking at them for too long, with no responses from registered letters sent to the owners, I took them home and used them myself. After about ten more years I sold them off and as far as I know, they are still running. The one I still have, and which drives the woofers in my home system, was a Dynaco accommodation sale of a factory wired unit; it is from the very first months of Stereo 400 production (early enough that the Whisper Fan� kit was not yet available) and it still has its original ceramic fuses, despite being worked on twice for bad transistors in the Class A amplifier section, stem-to-stern capacitor upgrades in the audio path, and a complete bypass of the PC-29 board.
