I recently picked up a 1960s Radio Craftsmen SET amp and recapped it with help from some of the fine folks here at AK. That thread is here, with pics.
Overall it's been playing great (except for some lingering post-Deoxit pot noise and the treble pot not doing anything after 12:00—) and I've been blown away by its warmth and musicality.
Two nights ago, in the middle of a listening session, the sound just went away. I thought maybe it was the end of the track near the label, and the Q-Up just kicked in before the song was over. Nope. No sound, no jewel lights, nothing, except that I was running my AR XA though the single switched ac on the back of the amp, and that was still running.
I've checked it out visually and nothing seems to be amiss (the fuse looks ok, and there are no exploded caps or burned resistors, etc—) All the tubes seem fine—there is just no power to them, apparently. (I did make a mistake and installed an X-capacitor instead of a Y-capacitor, but I figured that would last a while until I could replace it...)
I have a Fluke multimeter, but I'm honestly a noob as really understanding how to use it. Can anyone give any tips on what I need to do to troubleshoot the problem? Hoping it's not a transformer issue...Thanks in advance—
