I picked this today. Paid what matched and unused EL34 quartet cost for it.
So what I got:
-4x United Electronics 6ca7 (dating to 3/76?)
-1x Siemens ECC81 (*)
-1x Siemens ECC83 (*)
-2x TAD 12AU7 (wtf?
)
-Patridge 4-8-16 ohm OT
-Filament trafo 6.3/2A x 2 (*)
-PT 220V to 400(0.2A)-0-400(0.2A)-5(2A)-6.3(3A) (*)
-Chassis with some reusable components
(*) = identification request if ya please
So the circuit board looks good, but all e- and poly caps look bad. Wiring is messy, repairs are sketchy and there’s oddball innovations with paralled resistors and series diodes. So complete rebuild is needed here. Gonna disassemble it and test trafos before doing anything more.
And yeah, here are the pictures!
Does anyone recognize stamped logo on PT shown on the last picture?
