I’m there now Zman!!
My USSA5 is singing away with the SSR boards installed and they work perfectly!
Instead of using the SLB faston tabs to run the power for the very small gauge wire to the protection boards, I tapped off of the TP1 & TP2 positive and gnd vias with 22awg silicone jacketed flexible wire. Since it’s a dual mono power supply I did not want to run both boards off of one SLB for fear that the ground would be contaminated between power supplies. Also, the speaker return goes to its own channel SLB gnd tab bypassing the SSR board. In summary, the only connections at the SSR board are: amp in(+), speaker out(+) and DC power in(+/gnd). Four wires ultra simple
They work as described, nice 3 second turn on delay and when amp power is cut, so is any residual signal to speakers, immediately. Installing these gives your diy project a very commercial ”safe” feel to it.
Nice work Jhofland, JPS64 and X!!! Thanks.

I actually have 4, this is the main fixed soldering one, there is also a test bench with o-scope and other instrumentation, a hardware assembly bench, and a SMT placement bench with microscope. But I agree that the soldering one could be bigger.
No worry, I was speaking about my soldering bench being messy, yours I already know! LOL
