So I bought a ZPM board, populated it, boxed it, and had something odd happen. Signal goes through, but with no delay nor modulation effects. The signal just gets boosted a fair amount, quite cleanly too, might make a good boost if not for the other issue.
The 78l05 I bought heats up when it's plugged in and turned on. Not enough to fry it, mind, it still puts out 5V just fine.
All the caps are the proper values, and so are the resistors (as far as I can tell). The regulator doesn't heat up when I pull the 2399 but that's not telling me much either.
I've done the standard checks for bridges and bad joints but found nothing. This is confusing as hell.
I'd appreciate any help that's given.
Oh, and I put this in a 125B since that was on hand, so accidental grounding is fairly unlikely.
