"We believe mains was mixed in with the -12v rail."
LOL - very funny Simonty.
I would just like to say thanks to Glenn2 for his advise on changing CF03 (about 3 weeks ago) to increase the time it takes for my player to start up. It worked a treat.
Also, does anyone have an op-amp based Super Regulator design that is possible to build on veroboard? I'm skint and can't afford Audiocom etc.

(I think) times in there a few years ago.
Yep, that's Gatecrasher/The Republic. Monday nights some 8 years ago were great - 80p double vodka redbulls at Blessed. Great stuff. It went mega-commercial and changed its name to Gatecrasher to fully cash in. Also changed all music to god-awful pop-R&B. So it deserved to burn. Sad though, I have some happy memories. And when it was overhauled it had an amazing all-horn sound system with the best bass ever!

Now that you've mastered traditional PSUs don't you think the switching PSUs would be an interesting challenge? I've been told by some here that the switching PSUs can be improved quite abit. I put some ALWSRs and BGs in mine with some pleasing results.
For me a universal player was a good budgetary compromise. Allowing me to do everything with one machine.

P.S. If you'd like a copy of the DV7600 service manual drop me a note.
Changing PSU Diodes to Schottky type
After adding some 900.000 uF to my Marantz CD53SE Digital PSU and also altering the Analog PSU, the result was a more detailed sound. Now I want to change the rectifier diodes. Would a Schottky 1N5819 (1A 40V) be a good update ? I would like to try the 11DQ10 but I can not find any. Please advise because I am worried about the reverse leak current that is specd at 1mA. Also I am using a Sony DAT TDC-670 as a dac and the sound is much more detailed and spacious. Can you comment on this ? I do not have a shcema for the Sony so I did not tweek it....Yet.... Please advise.
Best regards

The picture is actually a CD-67MKII OSE.
I prefer the black ones personally!

My hum problem....
...goes away when I unscrew the cross-brace.
It goes across the top of two of the three transformers in the player. The original one and the Zapfilter one which is behind the transport. (Not the clock one.)
The transformer fields are perhaps inducing hum currents in the cross-brace that circulate around the casework and get picked up by the inductors in my circuit.
Does anyone think this cross-brace adds significantly to the sound? I might just ditch it.

I once fashioned a new cross brace out of a piece of solid oak for a cd53, but I'm not sure if your case is well-damped whether there would be a noticeable difference in the sound with or without. I just felt better with it in. There's a lot to be said for the placebo effect!
