It can operate at low power for testing with 3 FETs. You need to determine if there are other problems. That's why I asked you to install the FETs to see if it would play at low power.
Did what you said. Hooked it up to power. It did come on for a second then heard sparks looked. Q409, R161 smoked a little and possibly Q26. I only had a 5 amp fuse laying around. Popped fairly quickly.
Q414 is all burnt looks like a fried trace also. I am gonna try and post a picture>
An externally hosted image should be here but it was not working when we last tested it.
I went over it again this morning with DMM to make there wasnt any bridges and I am pretty positive there was not any bridges.
Do you want to continue to try to repair it? It appears that there is significant damage in addition to the output transistors.
Do you have or have access to an oscilloscope?
