    Under rated? Certainly there is minimal current involved, and we are not going anywhere near 100v. 1N4148 is fine. Or 1N914 if you have them instead. I also was a Fender warranty station for...

    Sure, you could do that. Or tack solder a jack into the circuit just during tests. ANy way you can think of to get a guitar signal into it.

    COnsider: Guitars have unbalanced outputs. The inputs on this amp appear to be XLR for low-Z inputs, and that is what the transformers are for. You don't need them, you can ditch the transformers...

    They are not stock. What are they wired to? If I had to guess, they might be on/off for each channel. I suspect this PA amp was used in an installed system rather than a travelling show. And...

    Let us not confuse terms. A "switching supply" refers to a power supply - short for switch mode power supply, often abbreviated SMPS. That is an alternative to big heavy power transformers. SMPS...
