That would be good for a clock, but not for your output stage where you want BIG VA. I have 50VA there, but the general wisdom seems to be more is better. If you want to order one of Brent's PSUs, maybe PM him and I'm sure he'll be able to help you find what you need.

You can totally fix the player. There's nothing broken about it, but you need to sort the PSU and those capacitors on long wires out, stat.
Your op-amps should be fine in the long run provided they are genuine, but the HDAM bypass is waay premature IMHO and that treble is going to be nasty until you improve other areas. Read the mods list(s) for hints on the best order to do things.

Not sure what's going on with that regulator on the right hand side either...

The external supply is just powering the output stage - in your case, op-amps.
It may also be powering the HDAMs if they haven't been disconnected properly.
I think you need to figure out if you're going to persevere with the DIY or send it off to one of our resident gurus. If you're going to DIY, I'd suggest you download the service manual and start reading the forum from the beginning. I know it's daunting, but everything you need to know is in here.

This looks interesting!

Swap the caps and I think it might be quite good for the analogue output stage PSU!!

Thanks uv this would save me a lot of money to spend on other bits for the player if its suitable. I notice its 15v and 0.5 amp is the voltage a bit high

That could be adjusted very easily but there is no reason it won't work at +/-15v instead of 12

Just need a 50va transformer, put your big caps on this psu board and away you go!!!

I'd be happy to help you to learn about what you are doing via the forum for sure!

If you wanted to build yourself PSU based on that module, then I could potentially show you how to configure and install it

Have you got the service manual yet?
