a seller on here has a Friedman modded XTC, but he has no idea what mods were done on it, can anyone help as to what the Friedman modded XTC has changed??
And one more modification of XTC module. It called "XTC MOD"
I was replaced electrolytic cap from 22uf to polyester 2.2uf, and I was placed switch "structure" with replace cathode resistor from 2.5k to 2 x 4.7k like this was in original preamp.
