Hi!
My fender stage 160 combo amp had some cold solder joints. I reheated the flux and took care of that. What I failed to take care of is putting the power wires back in the right places. I plugged it in and the cord exploded, and the magic genie escaped.
The fuse is still good and no burnt spots on the board, however the power inlet and transformer smells terrible. I think my transformer is destroyed so I need to replace it....and get the correct power wire placements. (P7 P8 P9 P10 P11).
The codes on the transformer are B-039129, then the Date encoding below that, then MS 1-28 below the date code (EIA606).
PLEASE PLEASE PLEASE I beg of any help or direction of where I can get a replacement transformer. Thanks in advanced!
Justin

update: Well I looked over the schematics CAREFULLY again. On the first page, in the box labeled 120V power (not verbatim) it shows what wire goes to what post. I will hook it all back up this evening, and see if my transformer is really blown or if something else.

update 2: Ok, my transformer is OK, nothing actually came in the amp the wrong way. It appears (looking back at the schematics) I crossed my neutral and hot from the switch and the transformer. I was lucky in that the only harm that it did was literally pop the power cable.

****IF YOU DO ANYWORK, UNDERSTAND THE SCHEMATICS & TAKE PICTURES BEFORE YOU WORK ON SOMETHING*****

I have learned from my mistake, hopefully it helps you.
