Im repairing a hifonics amp which uses A1275 and C3228 drivers for the power supply Can i swap them out with Bd139 and Bd140? If so do they ace the same direction or do i have to flip them around?
I'v got one of them on the shelf, could be rebuilt, but it's not really worth it, if you need that amp to help fix yours, let me know, I only have like $7 or $8 total in it.
I noticed a broken leg on 2 of the rectifiers i resoldered them and put them back in amp is idling perfect now. Now to put the outputs back in and test for audio
