Ok, So I decided to replace all the caps in my amp from my STD3 (its an SHP3 amp) I used the parts guide posted on Tony's Arcade site. I compared the values to the caps as I removed to make sure everything was cool. I replaced the caps, and met resistors as well as the driver transistors on the driver board, the caps on the pre-amp board, the caps on the inner chassis and the caps and transistors on the outer chassis. When I plugged the unit in a small stream of smoke appeared from the outer chassis transistor heat sink. I pulled the heat sink off and found that the smoke was coming from a 30 ohm resistor on the back side. The resistor is on the left side of the heat sink if you are looking at it from the front. I have posted a picture. I am hoping someone can shed some light on where I went wrong (if I did) and how I can figure out the problem. Sorry for the long post, just alot of information.
