Made a sort of "frankenstein" battery pack this morning, since I have a Meta42 coming in soon... what I did was took a small Radio Shack project enclosure I had lying around, the male plug + a few feet of wire from an old AC adapter, and a couple 9v battery clips I also had lying around.
Wired the clips up in series (+18VDC, more or less), charged up a couple NiMH 9v batteries (which I also had lying around luckily). Put the cover back on the enclosure and presto -- quickie 9v battery pack that... well, I guess it ain't really "frankenstein" cuz it looks like a mini battery pack.
Just for the fun of it, tried hooking it to my Creek OBH-11 (normally runs on 24vdc with a wall wart) to see what it sounded like:
Oh my goodness... a very large jump in sound quality there over the Elpac WM080 it was using, noticeable immediately. I think I'm a new convert to battery power! Gonna have to make another of these quick & dirty battery packs for when my Meta42 comes in the mail -- I may even have more of the right parts kicking around and have to buy nothing whatsoever. The SQ improvement with the Creek is just amazing.
Anyway... as you can see by my ordering a Meta42 rather than building one I'm not normally much of a DIYer (more like a hack who owns a soldering iron & cheap multimeter), but this was a project I could handle...
Question: Will alkaline batteries perform as well as NiMH for powering amps? Not sure I want to buy another two Plainview 9v batteries if I can get away with cheap 9v alkalines, and they last long enough.
