.3 ohms. Because of the torroids. I lifted the base off the board and checked a few transistors to make sure they were not shorted. I can check all of them if you would like but none of them are getting hot when I leave power connected for a minute or 2
Is current possibly passing through the reverse protection diode?
If you power up through a limiter, what gets hot?

So I assumed it was one of the torroids. Stupid me. Had 2 shorted transistors on ps side. Is this a suitable replacement. https://www.mouser.com/ProductDetail/Central-Semiconductor/2N6488-PBFREE?qs=u16ybLDytRb7vbIa3gGlXg==
Central wouldn't be my first choice but since the onsemi isn't available from mouser, they should work.
You need to make sure that all of the transistors that are in parallel (all on one side of the heatsink) from the same batch.
