Sony sa-wm40 power problem

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
