7603 HV oscillator doesn¡¯t start up


C G
 

Assembly: CRT Circuit (8)
New el. caps.
Transistors checked with multimeter (don¡¯t own a working curve tracer until the said 7603 is repaired. So stupid!). Read that TO-3 are factory selected and must have low gain, right?u

Mainframe power supply restored. All voltage checked within tolerances.

Any ol¡¯timer clue?
