I sure could use some help with this amp, originally I had a bad power supply and finally got that fixed, left chassis out of the cabinet and hooked it up and played it that way for a while. I decided it was time to put in the cabinet and thats when it decided it was not going to work anymore. Took it out of the cabinet and worked on it again, 2 power transisters, a driver transister and a open .33ohm resister and a bad solder joint later the power supply is working again. But now theres no output, everthing light up. I hooked up a audio gen to the speaker and it works, checked the input jack, hooked up a guitar at the input and the audio gen at the input and followed the signal all the way to the output. It seem to work but still have no sound. The last thing I did was put a cable from the line out to another amp and I got an output there. Iam new at this and any help would be deeply appreciated.
