Hi, this one was from the frame board, but there was another in the line stage too.
I'm still waiting for the 0.47uf 1000v to arrive, the last one to be fitted and then it should be all systems go!
Like the electrolytics, the Dubilier types were generally measuring much higher on a capacitance meter than their rated value .
I found all but one was in fact slightly leaky when tested at 500vdc (half their rated voltage).
I have been fitting LCR types as replacements and naturally, these have no leakage whatsoever.
Granted, the Dubilier plastic types are not as leaky as old wax capacitors, but in high voltage stages they are not trustworthy.
