MB Quart RAA1000

[mike49504]

I recieved this amp for reapir the power supply is totaly shot.

They are using FQP65N06's for the power supply fets. Wondering if i can switch theese to IRF1018 or do i need to stick with the originals.

The drivers are toasted also they are using KTN2907A and KTN2222A

Wondering can i sub theese for something else or if i need the same part numbers wondering where i can find them

Also the gate resistors are toasted i believe they are using 56 ohm


Any help would greatly be appericated

I'd suggest that you go back with the originals.

The 2N2907 and 2N2222 are likely equivalents but the 2n2222 comes in a metal case.

If you have multiple gate resistors that read 56 ohms after removing the FETs, you're probably correct.
