Still lurking around here, and stepping in when in dire straits

The Mundorfs are ok for the opamp supply, they are a bit large physically though. I would suggest some more filter tweaking yes (with polystyrenes being my personal favorites), and of course a good clock! (Flea, Flea, Flea...)

Seems like the bloke who had this one as just chucked any big caps he find in the player wether bad quality or not. I will get the player tried now to make sure the caps i have changed work ok then i will get down to to reinstalling the origonal power supply
Ok, good luck with this, if you have any more questions just ask. By the looks of it, these two jumpers are all there's to it. I hope that reg near the DAC is still properly connected.

No, the large caps are connected to the opamp supply, but the socket runs to the two 5V regs.

This is too painful!! PM me and send me just the main PCB along with the external psu and I'll tidy it up or at least advise whats worth keeping and sort for the cost of a few beers!!! You'd have probably been better off with a std one to start!!!

I think the white wire was soldered to the grd plane, but the PS was not a split rail?

I think those mundorfs should fit direct on the PCB in a 67?

Depends on how much the clock is and if its a clock 3 or a clock 4! Also what PSU is it and how much are you paying for it?
