Adcom GFP 750 preamp problem

Greetings,

I turned-off my system one night, and turned it on again the next night, but got no sound. I tried everything, but nothing until I flipped the switch from active to passive. It will work on passive only, and now there is a smell coming from the unit.

Any ideas? Thanks.

Not everyone here may be aware that the GFP-750 is a Nelson Pass design. From Stereophile's review, written by Wes Phillips:
The GFP-750 is a Nelson Pass design—essentially a variation on the Pass Labs Aleph P and Pass's DIY project .... The preamplifier that most reminded me of the GFP-750 was the Mark Levinson No.380S, which costs $6495.... I've gone just gaga over it, not simply because it performs well for the money, but because it begs comparison with the best preamplifiers I've ever heard. Period.
Also, I strongly second Elizabeth's recommendation that the unit not be operated in passive mode until the problem with active mode is resolved. Given that it is producing a smell, continuing to operate it could very conceivably lead to further secondary damage, or even a fire hazard.
