I was excited to work on this brownface Pro ... until I opened it. This amp was raped by a previous Tech. It is a sea of Orange. Every coupling cap is gone. The Orange terror has to go. I know the new Sozo are made in China but they will sound OK and look right. Even though the output transformer may have failed, I suspect it too was pillaged and replaced with a Mesa Boogie OT. Not one original preamp tube left behind.
The power transformer has me stumped. I measured it as a 110V transformer. There is a code "66233". I don't know of any EIA code under 100. Could Schumacher have accidentally left out a zero? If so, 33 week of 1962 sounds right..but an EIA of 66???
