Re: Crumart Trilogy replacement power transformer

Check the rectifiers and cap's downrange for shorts. I had a similar fault on a power rail on an Otari tape deck. Kept blowing fuse, I replaced both the rectifier and the filter capacitor after it, and that solved the problem.

Right now just having the transformer connected to the and power switch (with the rest of the synth disconnected) still blows the fuse. The primary checked out. The secondary show something like 3.5 megaohms. That was it. There may very well be more damage further on but as I said, I haven't got that far yet.
