Hi & thanks for reading.
I have been given one of these old dual beam storage scopes. It has several
faults, I have managed to get the EHT working after replacing 2 transistors,
but there was crossover distortion & low gain in the Y amp, which I managed to
bodge up OK, but I have no idea what the real cause is.
I have got the scope in a servicable condition, reasion for attempting to get
this scope working is its storage feature. It has already found faults on slow
logic at GB3HV so I guess the work was worth it.
Has anyone worked on these scopes before & got advice or circuit info for
it. I would appreciate any information on the unit.
