TA7801 making some noise after the REM turn off
Im having problem on my MTX TA7801 which the amp has no problem hitting the bass out but once I turn off the REM, it start to discharge and making some noise to my woofer.
I've been troubleshooting it for couple of month but still can solve it.
Anyone here can help?

Yup. Disconnected the RCA also produce some noice when turnning off. I have try to change the processor board from other TA amp. The result also the same.
Currently, im trying to check is there a discharge circuit for this amp.
Will there be possible also the JFET controlled the Optocouple failed?
Ahhh...so many possiblity which I don't know where to start.

MTX TA7801 FET ID PLZ
I have a MTX TA7801 that doesn't work have fets 104,106,108,110,112 all burned beyond idenification as well as FETS 103,105,107,109, and 111 broken in half but appear to be a marked n520ak. Does anyone know what these fets are and where I could purchase them?
