Tosted PW tranformer
I finally was able to do a bench test of a Tubelab SimpleSE that I've been working on for quite a while. In any case it sounds very nice! All for 10 minutes then I decided to flip the standby switch. The 5A fuse in my variac blew and likewise the 3A fuse in the amp's chassis. I replaced the fuses and this time I used a killawatt meter in front of the variac to measure current. The Hammond 274BX was buzzing loudly and drawing about 100watts at only 40 volts ac on the variac. I think the resistance on the 274's primaries was less than an ohm I think.
I think I shorted the primary my PW transformer.
Aside from making a doorstop out of the 274 is there anything I can do? Repair? Core exchange?
