Do you know what they use for fets in this amp? Someone got crazy with the soldering gun and put different fets in this amp also after i removed the clamps half of them arent even soldered in the board . Irfz44's are whats in the amp now with 68 ohm gate resistors.
Will the 44's work or do i need to replace them with different fets?
mike49504 i see u have tested the amp and now it works 100%.....i see u dont have alot of experince fixing ma audio amps. so my question is have u seen anyone using that amp (401sx) to its full potential? because i wanna run two of those amps. i had one previously and like it but i only had it a 4ohms and it was only one sub. any help would be appreciated. sorry if i "thread jack not intentional"
I have fixed several MA amps along with alot of other brands Just dont know what the correct parts are sometimes when someone gets into them and trys to fix them and they dont have the first clue on what they are doing.
Ive heard 1 of theese amps and its a pretty powerful amp i was surprized what the amp could do very clean and powerful.
