Just testing with the new wiring for servo psu only.
Much improved dynamics, bass and clarity. That servo is soo sensitive to mods.

edit: I mean the driver IC's psu not servo chip

Hi Lee
Now this is growing BIG TIME.
How much uF are you using for the smoothers (Total value ?)

Hi Ricardo.
27,000uF per rail so 108,000uF total.
To be honest, I don't really know if it sounds any better than using large-can, high quality smoothers, but I had them from another project so I used them.
Hooking up the output psu now so that could be a big improvement.

Edit: I've already beaten Brent in the total VA count. Ya rly.

Funny enough, I had this conversation with Simon the other evening. I've got a couple of the same boards with the same caps. I'd be happy with a single SI@ 22,000uF per rail vs the same cap banks. If you were really worried about getting the uF, you could always use 2 SI's per rail😱 but I really dont think its worth it unless its in an amp or other greedy application.
I intend to use 22,000uF SI's on pretty much everything in my 63. If I cant afford the addiytional SI's (Got 10 at the mo plus a couple of 10kuF mlytics) , i'll use TSUP's as an interim solution. I'm really not convinced on the cap banks even though in theory the ESR should be very very low. DOnt suppose you know what the ESR of each of those caps is Lee?

I just put something similarly naughty in my Alpha to power digital filter and decoder, except I've used CRC filtering to drop 8-9V from each rail as they were a bit high. Ripple should be quite close to zero. 60 Silmics used 😉
Just having a first listen now...

You guys are on a roll! and I thought this was running out of steam. I prefer to keep all the mods tucked together under one roof but I can appreciate the need for going out-board.
just kidding, Shep talked of "out of steam" for the thread, I find it's quite big weapons now, no one to test a new op amp these days, no one under 100.000µF =)
Hehe indeed, I think it's a bit of a competition sometimes. I'm up to something like 170,000uF in my player these days, 44,000 in my pre-amp, about 70,000 across my two power amps...
😀 Notre Français à le sens de la réplique! You guys are creating local power stations. I bet you could attach a kettle a toaster and still play music!
I'm sure your right but I have drawn a line in the sand (famous last words) and even if it means losing out on the really significant mods, at least I'll have the satisfaction of it all under one neo-retro roof. Mind you, there's still room in there for more...
Going external helps to achieve the icing on the cake and is messy and costly in time and often parts. You can do a LOT in one small box. Remember Brent's only just broken out of the box as I think there really was no more room in his cd63!!
