When I eventually get a way of running the 610 from Mike that isn't a fire hazard , I will update my software for the 3900 to drive it and the 7000s too.

Yup. That's how I'm going to be remembered now. Great. Mr. Fire Marshall. (I'm waiting for it now.. SNL? Comon..)

Anyways, did some testing this past week (with the fire alarm disabled!) and so far I THINK I may know what caused it. And it's one of those WTF on my part. Not because I assumed it'd be known, but because I didn't realize what WOULD happen if you DID do it..

The Empeg's wall wart can NOT be used. While the plug is the same size (or close enough to work), the POLARITY'S WRONG. This, in turn, sends +12 backwards thru the VR, which it was not meant to handle. I still gotta do a few more tests, but right now, that's the only thing that makes enough sence to warrant a quarter-sized melted carpet spot @ V99's house...

Still working,
Me.
