I would like to reuse my Carver power supply board for DIY amp boards. The board has 2 bridge rectifiers that supply different voltages. This would be useful for my project. There were thermal switches on the old amp boards. Can I use the board without them? Also, would this affect my speaker delay protection circuit on board ?

It should work imo. Everything to the right of the power amps in that diagram should function normally. The delay circuit needs to see the correct conditions on its inputs for the delay to work.
Q404 base (via all those resistors) monitor DC offset and Q409 base via R420 is the overcurrent input from the amp stages. I think that can be left not connected if not needed. I can't just see the thermal cutouts and where they operate in the circuit but that delay looks conventional with just those inputs.
