Perry is very correct, in earlier models the electrolytics around REG24 failed.
Can you confirm R6 R48 and R64 just after REG24 are 100 ohms ?
Do you read 5.1V accross D1 and D2 ?

The 3 resistors are in parallel measuring 33.5 ohms which is about right. Voltage on the Diodes is 5.2 volts before it goes into protect then drops to 0 in protect.
They all check good and I did resolder them. Still same results. I also forgot to mention I am testing this without it being mounted to the heat sink. Not sure if that matters.
Since you have around 33V rail voltage before the amp protects, you should have this voltage on one side of R37
No problem the amp is out of the chassis

Could I check for continuity between this resistor and where it connects to the rail? If so where? If I had the right schematic it would make it easier.
you can check continuity between R37 and the positive pin of rail cap.
I provide authorized service for Taramps in my country but i am not allowed to share any schematics or partial screen shots.

I do not see the same reading that I am getting on the input side of that transformer. I can only see the 33 volts P-P on my scope in the input side and the output has very little. One thing I did notice is that it appears that one set of the windings look burned. I don't know if you noticed that in the picture or not.
By using your multimeter, what is the DC voltage on the rail caps as the amp tries to power up ?
Do you get the same on R37?
Sorry i cant see the suspected burned of the trafo.
