Hello everyone
I have a problem with this subwoofer, I got it from a friend from Australia and I live in Poland and he is 110v and I have 230v, I reviewed the diagram and the main transformer I took from JVC RX-6010RBK / RX-6012RSL which gives me + 43v taps and - 43v at 75w bulb load dropped to 42.6v and I wonder if it can do it. I do not know, however, how to give an auxiliary transformer, it should be about 2x13-14v I would ask for the selection of this transformer, maybe some link to the store.
adds a page with the diagram SONY SA-WM40 Service Manual download, schematics, eeprom, repair info for electronics experts
Best regards and thank you in advance for your help

fine but as I already have the main transformer or the most expensive element, why do I need to buy converters, I only need to know the parameters of this auxiliary more precisely
Ok, i see, you are right. You want to replace the main transformer, and you have matching secondary. Great.
For auxiliary, any small transformer will do.
May be something like this?
