You are absolutely right J M the Bandit 75 has its place. I have a new respect for an amplifiers output.

The Special 212 has an external speaker jack and gives me 130 W RMS into 8 ohms I just need to get it up for the job. I re-soldered the bridge back into the board but no cigar. I'll pull and test it. The solder on this looks to have been actually splattered from the hole in the board.   

Found collector and emitter leads loose - can't imagine a current surge could blow the solder away? Re-solder and it sounds good to go. I hope this is my only problem and quite embarrassed I didn't spot this sooner. Now on to the next project - a Peavey Special 212 Transtube . Looks right off the bat like a power supply issue. The solder is blown away from 2 leads of the bridge rectifier.

This Forum is just fantastic for the information people have shared. As I gain more experience and knowledge in amplifier repair I hope to contribute in a helpful way.

Thank you

The output DC voltage measures around 200mv at power up and then stabilizes to 3.1mv after a few minutes.  There doesn't appear to be any unusual smell, heat or visual signs of damage. I don't own a signal generator or scope but am familiar with testing individual components and can use a multimeter and LCR meter. If someone could point me in the right direction I was hoping to find the problem. I have the drawings for the amp   

I had a make shift extension speaker connected to a Peavey bandit 75. Unfortunately he wire was tripped over and shorted. What damage could this cause? The preamp and speaker seem OK but the main power amp is producing unusual distortion.
