Ok So the Amp Had a PS75n05 (Q8) blown when i got it, it had several other Bad Fets on the power rail, also on the output rail. everything on it is new, both rails and ps fets 3205 and 4)MUR1520. Drivers were replaced as well, and all gate resistors. All the output fets are in the mega range. This blew the 10 Amp So i tried the 15....The amplifier powered on and produced sound; however, i dont think the clarity was right. there are some minor poping or static niose when you turn the gain or pop when you switch the subsonic switch.
The term 'rail' is used to refer to the various power supplies (i.e. ±15v rails or rail voltage for the output transistors). The metal strips are MEHSA insulators in Rockford amps.
The controls may simply be dirty. All they may need is a bit of contact cleaner and to be worked back and forth repeatedly until they clear up.

Ok thanks, i will try but it also just had like a non clear sound to the bass notes and output all together sounded off to me? crackling bass notes? I think it had a overall low output, it did increase as i increased the gain slightly. I used a dvd player as a input source, i switch the a/v cable, same result. The speaker was a infinity bookshelf speaker of 8ohms. Which i believe the amp fine at 8 down to 2ohms. Should i use a difference source with volume?
Parts used as follows:
On the PS Mesha insulator Replaced(6)75N05HD with (6)IRF3205's.
Replaced the (4) Rectifiers MUR1520
Replaced all 10R gate resisors
Drivers Q21,20 Replaced MPSA06
Drivers Q17,19 Replaced MPSA56
Replaced on Output Mesha insulator Q110-112 IRF6215, Q106-Q104 IRF3415.
Amplifier powered up with a 15 amp fuse and produced sound. it seemed to not be as clear as it sould of been maybe muffled, crackling bass notes: I would like someones help. I believe my part choices were good and i would like opinions and suggestions.
