I just purchased an audio buddy preamp. Could anyone recommend a battery set up that I could use? Would the Initial RB-270 UNIVERSAL BATTERY with the audio buddy or could recommend a commercial battery.
Thanks

The Audio Buddy runs on 9v AC not 9v DC, so the initial battery won't work. No battery will work. For portable use, you'd need to get a 12v battery, a power inverter (converts DC to modified sine wave AC), and use the wall-wart plug that came with the Audio Buddy. There used to be companies that made an all-in-one 12v battery plus inverter unit that would make for an easy solution (eg, the Vector Pocket Generator). Don't know if these are still made.

okay, i have to bump this because I'm in the market for a pre and just spied the audio buddy at the oade site.
Todd, what do you think the feasability would be of digging into the box and patching in past the rectifier? Surely this thing doesn't have any components that run on AC right?
Or, upon further contemplation, do you think it will have a multi-tap transformer for several DC voltages?

I really have no idea what would be in there, but it may indeed use several DC voltages internally. You could probably do the mods to make it run on an external DC battery, but I'm not sure it would be worth the effort for this preamp. I seem to remember that the Audio Buddy had a pretty low threshhold for input overload, but maybe someone who has had one and run one could comment.

Thanks for your input Todd! I'm going to look a little more into this and check the specs out on this. But if it has decent phantom and sounds alright I might give it a shot. I figure it'd be a good winter project... get my electronics skills back into shape. Plus the box is under $100, so not much to lose.

I know the M-audio mobile-pre works as an analoge front end if you connect it to one of the 5v usb battery boxes out there, and you get a mic pre for your computer as well.
