Recognize this PSU PCB?

[Mylithra]

I have several of these I bought from Gustav years ago. I've used a couple but I have a few more I want to use but lost the schematic for it. I know this is pretty simple but does anyone remember this PCB and have the schematic for it?
Thanks

I don't want to seem unfriendly, but you can work out this circuit yourself in 2 minutes by following the traces on the PCB. You can do it!

im a mechanical engineer not an electronics expert, but i have a hunch all thats needed is to identify the three semiconductors. and hay presto a daul railpower suply

for +/-18V and +48V as notetd on the PCB:

from top to bottom

LM7818
LM7918
TL783 or LM317

other voltages are also possible, depending on your requirements

I know that I need the aforementioned silicon parts for the power supply. I'm pretty sure I remember those C1-2 and 5 being 1000uf, C3-4 being 100uf, C6-11 .1uf, D1 = 1N4001 or better. R1 (120r) and 2 (4.5k) is a voltage divider to set the reference for the 317.
I'm not dense. I just wanted the schematic for reference purposes, I got the board here, I was hoping someone might have it without me having to recreate it from scratch.

This pcb was supplied with the original SSL 9k preamp boards that ssltech designed. It's not massively difficult to work out what is going on just looking at the pcb, but see attached if that is too much effort.

Thank you much.

The ICs in the straight-forward bipolar section are 7818 and 7918, but the 48v section needs clarification.
