SP-8 Preamp Kit. Built, was working, had a minor ground loop hum but not a big deal. Blew some fuses early on then stopped, seemed fine.
Now blowing fuses all the time. I've taken all the secondarys off the board. Still blowing fuse.
Disconnect the primaries, fuse holds. Connect the primarys back, fuse blows.
Checked several times and circuit is correct (was working!) and can find no incorrect connections or shorts.
Is it my PT? How can I check? I looked for shorts from primarys to secondarys and the extra purple ground and found none.
Also took the PT out of the case and can find no evidence of damage or shorting to chassis. Even tried it outside the case with the same result, blows fuse.
Any help appreciated. This is an Antek ASIT250 torroid.
Bummin.
