SMALL UPS...

I therefore, might be chasing something that is simply impossible to do, and the low-voltage concept - perhaps adding a simple diode-gate to prevent the external battery from trying to back-feed into the output of the on-board PSU if the mains fails - might be a good idea after all. I just did not really want to hack the amps, but sometimes..... EDIT: And a small SLA battery, would be able to run the amp for hours on end no problems due to the tiny load the amp represents, so there is that.     Edited 2024-05-30 09:25 by Grogster
