I have a Kenwood KAC-1023 that I have had for a few years that I would like to fix. About 2 years back I ran this amp at 2 Ohms bridged (knowing it was a bad idea), it did this for nearly a year. A climate change ended it's life. It normally ran warm, but when the outside temp went up it couldn't handle it. The fans would almost always run and the heat sink would run hot. Well like I say one day it could take it no more and it stopped working. The board does show some sings of heat and two of the lager caps seems to have leaked, all of the fets look fine though. I have included some pics and if any of you have possible parts and spec info that would be great.

Screw those transistors back down to the riser plate before you apply power.
What does it do when you try to power it up?

The amp is all back together at this point.
Well the amp lights up for a split second the it over loads my power supply (an old comp. power supply), no fuses blow.

Did you check for shorted output transistors?
As a side note, the caps may not have leaked. The substance around them appears to be a fixative.

The power and ground terminals, I located the black lead on the Neg. and used the red to go through all the legs.
You don't check output transistors with the probe on the power terminals. Have you read all of the basic repair page?
