I got one of theese amps in for repair and i need to order some parts for this thing.

This amp was taken apart by someone else and alot is missing off the board.

I missing the fets, outputs, power supply drivers, gate resistors, the rectifiers have broken legs, Class D board is fried, and ect..


So i need to order some parts but need help with a few of them..


Power supply fets are IRF3205'S Correct?

Gate resistors are 100 ohms 1210 package??

Missing the power supply drivers : Q24 Q25 Q26 Q27 anybody know what part numbers they are??

Outputs are IXTQ36N30P correct??

And anyone find a good source for the rectifiers : MOSPEC F30D40D ??

Ok going through this amp one more time and found that the blue crystal on the class D board has a broken leg..

Its marked 250MG

Anyone have a good part number for that??

 

[mike49504]

Ok got parts in for this amp..

The orginal power supply drivers im replacing with MJE171 and MJE182G..

Will the MJE182G work as a good replacement for the MJE181 since i couldnt find anyone who had them..


Also is it the MJE171 or MJE182g middle pin connect to ground??

 

[Perry Babin]

The 171 will have it's middle leg connected to ground.

The 182G will work.

Thanks.

Do you know what goes in board location Q22 ?

 

[Perry Babin]

I can't tell on the photos of the 1500. If it's the same as the 1000, it's a TIP42C.

 

[carampsguru]

Yes,it is the same

[mike49504]

Do the drivers for the power supply fets face toward the power and ground terminals??

Do you know the value of C13 ?

 

[Perry Babin]

Yes.

Got everything put back in this amp.. Powers up and idles fine ..

It produces audio but distorted.. Any ideas??

 

[Perry Babin]

Do you have clean audio on the 'IN' pin of the class D driver board?

Do you have a clean rail to rail square wave on the outputs?
