    Hey Bass Gang- I just signed up and this is my first post!! I need SERIOUS help!! Don't laugh at this:bawl: but my band just played a gig with a Japanese band and I accidently plugged my Ampeg Classic Bass cab into their power converter (100V). Played our whole set- the amp stayed on but it was smoking (didn't realize it was me cuz there was a smoke machine going too!). When I got home later to really check it out- I was screwed!! Now it comes on but it makes a REALLY CRAZY BUZZING sound- the polarity lights are both red- and cant be made to turn green. One of the (big) tubes (6550 power amp) were out- so I went ahead and replaced all 6. I also replaced the 1 (12AX7) driver tube. It still does the same thing!! I know I really MESSED UP!! I NEED HELP PLEASE!! WHAT TO DO-WHAT TO DO!

    I can only assume since you played the gig that you plugged your AMP HEAD into their converter? With the low voltage you probably overheated some resistors as well. They are not expensive at all but you need an amp tech to find them and check everything over. Hopefully the transformers didn't overheat, that IS expensive.

    Yeah- you're right B-String. It was the amp head- I think I forgot to mention that. I was hoping that it would be something that I could fix........but I guess to the shop it goes!!! THANKS FOR EVERYONE'S ADVICE!!

    Yeah anytime you see smoke protect your investment by taking it to a tech, unless you are one. Minor troubles can become major ones if not taken care of promptly. :)
