Ok, I got this unit and it has power supply problem/s in the regulated power supply side. Transformer , rectifiers and filters all test good.
Checking for 34v at emitter of Q23 shows only 22.1dcv. I am at a loss where or what the problem is here?
Took some voltages , maybe the more experienced can deduce something I am not seeing....
Q21 - E 15.9v ( supposed to be 33v)
C 0.99v .(? v)
B. 15.1v .(33.2v)
Q22 - E 15.8v .(33v)
C . 0.95v. (1.3v)
B . 15.25v .(?v)
Q23 . E . 22.1v .(34v)
C. 39.7v .(42v)
B. 23.5v . (?v)
Q26 . E . 16v. ( 33.2v)
B. 16v .( 29.6v)
C . 23.1v. ( 34v)
Q27 . E . 0v . ( ?v )
C. 23.5v . (35v)
B . -8.8v . ( -5v )
