repair or replace Chilton QM3 console power supply with schematic

[mylesgm]

So I'm looking for some opinions on the QM3 console powersupply.  I have a slightly damaged one here but am wondering whether I should repair it or replace it with a different supply.  The 48v rail has always been a little weak and is only universally switchable so I was intending on replacing that anyway but maybe I should replace the whole thing?

Any thoughts and suggestions on a replacement if replacing the 24dvc part?

A standard 7824 reg would be better, 150mA is only barely adequate.

Other than that, seems fine. My friend had a 24ch QM3, PSU did pretty well.

..but your power transformer may be under-sized for higher current draw...

I think I'll replace the 48v with a JLM supply running from a separate transformer so that shouldn't be a problem but do you guys think that a 3amp supply is enough current capacity for a full 24 channel console with 16 monitor returns etc...?

ok, so the transformer is burnt out and so I will be going ahead with a completely new power supply, multiple rails with over filtering.  Any suggestions as to particular schematics I could look at?
