So.
Good news.
Death cap is out, three pronger in & testing for continuity. I went to test & everything functioned as normal. Then I realized that I'd mistakenly plugged directly into the variac, and not through the lamp limiter as intended. Shut down & powered up through limiter- amp did the loud hum, pass no other signal, no power light business again. Now, I've used this limiter with a '65 Super Reverb and a Univox U-1246 bass head with no problems. They each run just like they're plugged into the wall. Not the Standel.
Is there any explaination for this? Does the limiter not allow enough current to flow to this amp in particular? If I hadn't previously used it successfully with two other devices, I'd question my wiring.
