Help with Modified Audible Illusions Modulus 3

Those are good sounding caps and may well sound better then the originals. But they are not originals.

If the caps that were replaced are shorted or the wrong value it could cause the preamp to be unstable. I am always careful to use the same value parts in any preamp I update. That preamp also has solid state regulators in it and that could also be a problem. Do the tubes light up?

Clearly, someone has added some green cylinder-type devices and circled them with yellow wire. They have also added some silver and yellow ones and done the same. There appears to already be enough wire, so why add more I have no idea. Very, very odd mod if you ask me.

First instinct is to say, WTF; as AI interiors are a thing of beauty. This one sure ain't! However, on a second look it seems as if they by-passed some circuitry. Do all the switches work?
