Five Fish 2448 mk2 Power supply

Hi!

I just got a 2448 mk2 PSU from Five Fish audio and I want to convert the 48vdc rail to a 9vdc rail.

Can somebody help me identify what parts in the rail need to be changed in order to get closer to 9vdc and allow the trim pot to get me there?

I added the schematic of the PSU in the attachement.

If I compare the 48v rail and the 20v rail, it looks like if I remove C18 and jumper R1, the 48v rail will look almost the same as the 20v rail, which should  make 9v easier to obtain with the variable resistor.

Only C2 remain higher than C10, I don’t know if it’s a big deal...

I definitely don't know what I'm talking about so thanks a lot for any help!

Ok nevermind!

The PSU I have is the latest one (not the MK2 but the 2448PLUS+) which include a 4th AUX rail that allow me to put any regulator I want.

A 7809 will go there and give me the 9v I need.

Thanks to those who looked and tried to help!

Sounds like a handy design.  I think Five Fish do great stuff!
