Title: Jamman battery powered, was: Jamman Schematics

> hey duncan (hey charles),

> well I think our issue is similar. meanwhile we got to built a 12-14v lead battery powered dc-to-ac converter in the works, which will eb anyways useful, not just for the jamman, because many better devices, like a real nice compressor for instamce work with AC 9v power supplies.

> will be awesome. that way I can play in parks and such (must do that for the exoperience of doing it.) 
> my roommate has already builtme a lead battery powered X-Hi-Z input amp with built in insert and bigg muff EQ... I’ll send pictures along with the test report in a few...

> I've had an educated poke around inside the jamman once or twice, but I haven't cracked this yet. schemos would be useful..... you'd think, on first examination, that the 9V ac only goes as far as a rectifier & then a 5V dc regulator, & that simply giving the jamman enough current at 5V would keep it happy. this appears not to be the case. I wonder if one of us ought to drop a line to mr sellon?

> what I'm trying to do is a bit different than jayrope's issue- I want to find a suitable universal power unit (like a laptop supply only smaller) to run the jamman off. these units all give out dc, so I need to figure out what's happening to the 9V ac (once it gets into the jamman) if I'm going to replace some of the process.....
