Schematics for Bogen MXM-A Mixer?

Not open for further replies.
Was given one of these with a bad PSU cap.
Fixed the cap.
It works but is probably oscillating intermittently, and very nicely picks up the local radio station.
Fixing it with my older son for his music interests.

Seems a lot of tube gear has no input RF filtering, when it certainly seems to need it. Hmmm.
