I bought a broken vacuum tube oscilloscope scope that was dropped, (turns out the transformer is burnt out too). The CRT was knocked when it dropped, and there's even a little bit of debris of something loose inside.
Actually the whole PCB cracked in have and 2-3 resistors. I fixed all that, then discovered the trans was shorting.
I have DMM, LCR/ESR meter, scopes. Is there any low voltage tests I can try to determine the state of it ? I have various HV sources, but I'm not messing with any of that yet
