I have a Dynaco Stereo 400 amplifier for sale here. I got this a long time ago and intended to rebuild it but haven't had the time. I didn't work on this, it came to me like this. This is in pieces in a box. It appears to be mostly complete but the knobs and whatever goes between the fuseholders are missing. One amp board is missing a pair of small transistors. This seems to be a very early version of this amp--the wires have labeled numbers on them and it uses barrier strips for a lot of the wire connections. A previous owner drilled a hole in the faceplate center to add some sort of wired switch. One meter's wire connections have come off.

This is obviously non-working and will need rebuilding. It is located in Glendale, WI, and I cannot ship it.

Text or email is preferred.
