What may I use from this?
Loads of Panas FC 1800/63, former opamps caps (470/25 RJH), some older Nichi PL...
Maybe just Tx, big caps (FCs?), 7805, caps (RJH?) and go? Maybe I'll re-use the RJH fitted on each rails on the PCB?

Hi Matthieu.

I have found that the best thing is to put the regs as close to the supply pins of whatever you're feeding as possible. ie. for the dac analog - Put FC + 7805 on small piece of stripboard, solder on some legs and then feed the output straight onto u199 (remove u200).

I have used a SuperRaygulator:

I guys. I've been busy lately sorting my psus out and other such things like QA assurance (very exciting).

Had a quick scan through all the posts and it's as busy as ever.

OT:

Anyone here have a copy of the service manual for the Rotel RCD-965BX LE discrete ? I have one on my hand and I'll like a sneek peek before actually picking it up.

I'll maybe go for a separate TX and 2 Raygulators (So from 3 regs to 5... when Brent uses 21!!! oh my...).
What's the values of the parts for a 5V Raygulator? And where to put the FC? They're big, they should stay by the TX, then wires, then the Raygs acap the DAC.
As it's endless, I think havin' Brent's SReg by the opamps and the DAC is far better...

Hi guys, how do i get my hand onto the Flea PCB?Has any one built superraygulator?Any pictures?-
I try to build Raygulator but struggle with parts-ie i can't get my hand on 121R and 1K05 resistors-only 120R and 1K or 1K5 only -actually are they the same as 1K05? Quan.
Has anyone heard of Gold minireg?- from Coffin-Taiwan.

Quan, I'd email Martin Clark off this forum for info on the Flea pcb.

Anyone who wants info on the "Raygulators": It would be best to use the "search this thread" box under the posts on your screen, you will easily find all the info there as there's plenty of it.

Cheers,

Lee.
