Since RJM has got the boards from Olimex, who's building, and for what cartridge?
To start:
Me, Lyra Dorian.
(needless to say, i'm stoked.)

I've built it already, although slightly different version and p2p. Using with Shelter 901
An externally hosted image should be here but it was not working when we last tested it.

Peter - as usual your craftsmanship is more than amazing - it's mind-boggling...
A question for you -- what's the copper plate in the middle for???
Thanks,

As usual excellent work. Have you compared it to any other phono stages?

P.S. We need more pictures.

Indeed, shunt regulators worked very well for me. I'm using something similar to this: http://www.mneng.net/PDK_Shunt_Regulator_files/schematic1.pdf
Hi Peter,
I like the way you applied the regulator boards. I have thought about that some times, but didn't find out how to apply the final connections between the boards in case those are in the middle of said boards. This allows for a tight signal and V+/- routing. Nice!

Peter,
You indicate that you use 627/637 that raise two questions:
I asume 627 first stage and 637 second, correct?
Did you do any decoupling on the opamps
Thanks for the info.
Did you compare 27/37 with 627/637, if so what is your impression the significant difference?
Your geometrical solutions and machining skills always envy me.
It looks great (and probably sounds likewise)
Regards,
Michiel

Yes, 627 is first. Due to a tight layout, there was no need for additional decoupling: BG STD 100/25 is the only cap I used per rail after regulator.
I didn't have a chance to compare 27/37 with 627/637 yet. I used OPA627 in a VSPS and it worked very well there, better than AD797.

You set a high standard...
As usual.
One question... rectifiers in the separate PS boxes with the transformers or are they in the main box. It looks like they are in the Tx boxes, but to be sure, I'll ask.
TIA!

Exceptionally neat, well conceived and implemented Peter!
