Recently restored. Came in with a shorted power rail. 100% of all electrolytic caps were replaced on this unit and the power supply was rebuilt. All the controls had to be cleaned. Other minor functional issues were addressed and this sounds and plays great. Cosmetically it’s pretty good. Few normal marks on it from normal use and transport. Please ask questions if any. I’ll try to get better pictures soon. The studio room where all that happens still isnt done yet.

Update as of 3/3/26
Memory batteries are now in a new 2x AA holder for alkaline batteries like it had originally and its using procel constant long life industrial batteries.
