MTX Thunder 2300 X
I opened up this amp for repair and its missing all of the power supply fets and outputs among other things..

Wondering what Power supply fets are good to use in this amp ??

Also what outputs are good to use ??

The board is marked TA2300X REV F

I use 3415s as outputs and 3205s in the supply.

replaced all the power supply fets and outputs .. Checked the source resistors all check fine..

Right channel has distorted output any ideas?

Have you set the bias?

mike49504 8th May 2012 02:36 AM

No.. Whats the Bias suppose to be in this amp ??

And do i measure across the source resistors?

Perry Babin 8th May 2012 02:48 AM

Set it by the current draw from the 12v power supply.

Set the bias in the amp...

Right channel is still distorted

Perry Babin 9th May 2012 09:48 AM

Were you able to set the bias in the distorted channel?

Post a photo of the distorted waveform (100Hz preferably).
