Quoted from Billc479:I think the transformer and rectifier board are one complete module. That means a few screws and connectors are involved- no soldering.
This is correct. You can swap out your transformer and rectifier board as a complete unit with your Mata Hari. Just disconnect the 3 connectors and remove the xformer and pcb, keeping it mounted to the backing plate. Probably a good chance your rectifier board has an issue. Once fixed, I would also highly recommend repinning (or replacing) the rectifier connectors, especially if there is any browning/burning on the connectors.
