I wish I could use them also in the decoder and HF amp and servo driver !

The difference compared with normal regs 340, 317 etc is outstanding !

Is there a way to calculate the "eaten" DC through caps? I mean knwoing the DC at DOS then calculate the cap size. Or just "try"? 3.3 enough? 4.7 perfect?

Thanks, Matthieu

It depends on the load by the cables and amplifier. At home my cdp was fine with 2.2uF but on other systems it suffered bass roll off. 4.7uF works in pretty much eveything i've tried.

If we go upstream far enough we get to my head

I fear it's too late for any refitting there. What will give up first; my mind? my Marantz? my bank account? my patience? This thread (already a legend)?
You all realize this thread has become an exquisite form of self-abuse

It would be interesting at some point if someone pitted a fully abused 63' or 67' against those 5000£ dreadnaughts, just for the fun of it...

Brent has already been there with a player in that sort of territory, it was close.

Hi all.
Please, i would like tweak a 67 with separate supply of Dac, uCon and Decoder.
So i need, please, some little example, and, as i would use some tranny for it, i need some suggestion about transformer type and abount logistics inside player (with some pictures too??).
Is it possible?
:-)
Thanks

Simon, I think it was close after Brent had modded the £5000 player, lol.

Cheers, Lee.

Hi R

To save space and € I would use one Ultra PSU with built in Spower. PSU for clocks and regulators

If you want to use extra locally placed regs, you can tap these before the spower in the psu pcb.

Ok for psu, thanks.
But i'm curious about separate regs position in pcb...e for some pictures about this job, 'cause this 3d is enormous and i have not much time for...
