Hi guys, I've received a replacement flyback transformer for the VT330. I'd like some advice about what other components it would be worth replacing at the same time. The transformer suffered from arcing but there doesn't appear to be any physical damage to any other components. I've got a replacement output transistor on the list, could anyone advise as to what else would be worth replacing - I'd like to get the terminal back to working condition with the best chance of a few years more use? My gut feeling is to also look at diodes and high voltage capacitors on the output side of the transformer, as well as the two large electrolytics on the input side of the power supply. I'm presuming that resistors don't normally need replacing. I have to weigh up the benefit of replacing components with the possibility that I don't get an exact replacement and balls something up. There are several high voltage (1000V+) capacitors are polypropylene. Do these typically stay stable over time? I have a circuit diagram and could put together an exact schematic if that is useful in helping. Thanks for the advice, Mark.
