Today i decided to move Am6155 222  to 240 VAC after proper jumping of amp and changing connector for VAC. I turned amp on and a fuse blew. I found out previous person who tried to run amp had a 3A fuse instead of 15A. Replaced and still would not run, no blower noise. After an hour of checking, and checking. I tried to get it to go comparing it to my 432 AM6155 and heard blower turn on for a second and smoke came blowing out of amp.

Upon pulling the grid bias section say that the transformer smoked and burned pretty good. What Luck. These amps are getting rare. I'm going have to find someone parting out a unit. I think I'll drag out old amp and replace tube socket on pair of 4CX250's and see if that will run. I still have supply that never smoked for the 15 years I used for the 4CX250's.. If anyone knows of someone parting out AM6155 let me know . Thanks Mark, K8MD
