Hello group,
I'm working on a TA92001 amplifier. the amplifier got dropped and some of the power supply components are missing. I need picture that shows the little xformer driver in the middle. not the power supply driver but the next one to it. I have to determine polarity.
Thanks

In the photos I have, there are no visible polarity markings. What are you using to determine pin 1?
Since I have no schematic. I assume that the thick windings were the primaries and put them towards the group of rectifiers diodes in the picture, probably wrong because most go towards secondary. This transformer seems to have 2 set of secondaries wich make it a little hard to determine direction. I'm not sure if I put it right because amplifiers turns on but no output and thermal led on. I might have to do an schematic myself of the circuitry. MTX sucks and all the products they sell too, I know because I worked there. Thanks for your help!
The primary winding (the only single winding with only 2 terminals) will have 12v constant on one terminal and the other terminal will go to the center leg of an FET (likely FET501).
