I've bought Oscon caps at RS Components and Conrad.de...
Sonics are a subjective thing...I like oscon in the cathode very much...they are not very tolerant to overvoltage though.

Thanks Stixx and Radioman62. I have bought parts from Farnell in the UK before with good results. I checked and they have OSCONS, except for the 2.2 uF, 16V.
Any North America DIYers know of OSCON suppliers in our hemispere?

For this nest GB, I'll setup a wiki, then you can do your own edit and add to the total. Then if we can have 30 minimum, we are free to go.
Naturally the more we have, the lower the price, but I don't want to have to ship 100 boards, won't have the time really, see below...
By the way, just sold my house for good, until now it was only a conditional sale. Meaning, I'll start packing box, and taking my workshop apart. This GB will need to be before my move in May.
Stay tuned.

In five months we can reach 30 requests or even 100. At that point somebody can take care of the distribution, let's say, in Europe, Asia, etc. just to avoid you too many troubles.....
I can do that for Europe, if you wish, even if Italian Post is not the very best......

This is good news. I will order some through the Wiki when it is ready.

Hi,
I have been following this very interesting thread but need som advice.
In the manual for the Sprenger Regulator is written that the regulator only needs "raw DC". Can anyone tell me what this is?
Is the ripple a percentage of the B+ (1%, 0,5 %, 0,1 % or???) or is is a recommended level of ripple in mV or???
I tried to mail Mr. Sprenger directly through this forum but unfortunately this is not possible.
Any suggestions are very much appreciated.
Kind regards
Karsten

Raw DC: unregulated V DC. In practice an Xfrm, a bridge and a cap
Ripple: the lower the better, but w/out getting crazy for it
Anybody finished there boards yet?
I've just finished soldering the SMT i/c and had to order a few missing caps. Has anyone found a source for the 4.7uf Oscons?
Has anyone begin using their boards and or tested yet?

Re: Anybody finished there boards yet?
I'm in a final progress so very soon I will do tests. I'm ordering the heatzinks now but I would like to get some equivalent to LND150 or BSS135 which I can't find locally. Only BSP135 as sot223 case at RS-online. Anyone here that has to many leftovers?
I wll also also do something very dangerous....
I will use the very good audio OP from National Semiconductor, LME49710, instead of OPA655 or the SOIC OPA656 and also LM317 instead of LT1085. It seems overkill to order two OPA656 overseas when I allready have the other stuff at home.
I think it would work and not be to empirical in testing it out.
The LME49710 have also very low distorsion, high bandwith and a PSRR and CMRR of marvellous 110dB.
Any thoughts on that?
I've never dealt with shunt regulators before so this is a fun project.
One of the Regulator cards will sit in a tubed phono and line preamp that I will build later on.
Lets see which one of us would be the first with a working unit, of all those PCB's Sylvain sold.

Did some more reading and found out about Mouser.
At last it seems that I can gather all the parts. 🙂

The wiki page is still ''Work in progress".
I'll try to start the wiki when it will be availble.
