The main problem is the power supply, I got all crappy

don't have $$$ for that. Now I know why consumer products vs
commercial products have a 10x difference in price.
A short-term solution might be to fabricate an external shield over
the troublesome components out of sheet steel.
Another approach would be to physically separate the power supply
from the amplifier. That used to be a very common
approach.
