hi,
I've just come upon this idea by Dave Frost, here: https://www.thegearpage.net/board/index.php?threads/building-a-battery-powered-pedalboard.1131722/#post-14021222 and I really like it... the point: when you have 2 x drained 9v batteries, you don't have to throw them out... you can use them, for long, and they will provide a fix 9v power source... I haven't tried it yet... haven't built it, haven't tried it... the schematic came from the TS78L09's datasheet... I wonder if this is a good idea...? .................. EDIT: NO, it is not ↑ it doesn't make sense to use this with drained batteries... however, using it with two fresh ones, we can get a stable and fix 9v, which might make sense... ..................  - - - - - - - - - - -  |
