It's good nothing blew up....
So I powered it up.
Silencio.....muerto.
Tubes no lit. Muy pogano... I mean very sehr schlecht.
Quick check showed full rectified voltage across 200uF 10V cap....so I found out my photos deceived me and I connected a GND from a portion of the sch to the B+. Yikes! Rookie mistake.
Moved the wire.
Dead silence.
Output xfmr ok..... No B+.
Well....bad half of the power switch. The AC part is good, the B+ part is bad.
Opened the switch....it is not really serviceable. The contacts are under the moving sector that is co-axial with the pin holding the lever, and the pin is a rivet.
So.....I put lits of Red Deoxit D in it, literally flooding the can, and worked the moving contact.
Tomorrow will show. Worst case I will short the switch even though it means the B+ will be always connected if coming from battery.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
