I read another topic about a tsl122 and Enzo i believe said that he dealt with an amp that had a shorted out 16 ohm output jack. ive noticed on mine that you cant even get a speaker cable end to go all the way into the jack. I looked into the jack with a flashlight and it was blocked by a warped piece of plastic. Otherwise, from what I've read on here it sounds like I'm going to have to buy a new output transformer. Should I get new tubes first and see if that fixes the problem?
