+/- 16 and 24V from ACDC vers2

Post by nicolafantozzi »

Hi all!
I have an old ACDC version 2 and I need to pull 24v from the 48v rail. I’ve tried bypassing C1 and C2 and removing the double/tripler jumper but the voltage is stuck at 36v... what can I do?

Thanks,
Nicola

If the rail had been set to 48v before once the mod is done there will be a lot of trimpot turns before the level will drop down to 24v.

The 36v shows the mods are working but you will have to turn the trimpot lots of CCW turns before the volt start to drop and be set to 24v
