Upgrading Quad44 PSU

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

Hi,
I've been busy with upgrading my Quad 44 pre for a while now. I've replaced all TL071 opamps with BurrBrown OPA604's and I would now like to do some work to the power supply.
I've read that the Quad 44 psu isn't regulated. Therefore I would like to add two voltage stabilizers (7815 and 7915). But is this possible?
I've scanned the schematic of the psu and it can be found at:
www.cobweb.nl/rbrezins/index.html
I'll try to post it here but I'm not sure if it works.
Would it be possible to add the two stabilizers at the point where I've drawn the arrows in the schematic? I'm not sure what the transistors are for.
In case that someone has other or better tweaks/upgrades please let me know.
Best regards and thanks,
RB
