I have tried the scope, that seems to work; otherwise I'm more
interested to use it as a software define radio. But I have put
it on hold, I must finish those low noise preamps first. I tend to
have more projects in parallel than I can handle.

There is a picture in the thread "No RF Gear here?" in the lounge.

Jan, I noticed in one of your replies in another PS thread, you stated that the 120uF caps in the "Super Regulator" should not have low ESR.

First...120uF caps aren't as common as 100uF caps.

Second...after doing some searches at Mouser, I came up with these 120uF caps which have a ESR of 514mOhms:
860020675017 Wurth Electronics | Mouser

I've never heard of or purchased Wurth caps before, but do you think they will work okay in the "Super Regulator"?

Thanks.

I have a bandelier of Panasonic FC -- 120uF/25V -- 200 pieces @ $0.40 -- how many do you need. NOS from Mouser.

The first electrolytics specified by WJ in the 1995 articles were quickly obsoleted. The Panasonic FC has also gone unobtanium in 25V, but generally available in 35V at the usual suspects.

I certainly don't need 200 pieces, but it's good to know that you have a good supply.
My understanding is that the Panasonic FC, FM and FR caps are all low ESR caps.
Are you saying that low ESR caps will work just as well as higher ESR caps in the SR?

The low ESR comment was for the cap on the output. This cap plays a role in the stability and should not be low ESR like some boutique film caps. This is most easily fulfilled by using any cheap electrolytic at that position.

The other electrolytics can be good quality and low ESR if preferred, but will have very little if any impact on performance.

You only need 4 per regulator, for a total of 8.

I just put a 120uF/25 V Panasonic FC and a 35V version on the VNA so you can compare the ESR.

I'm about to order parts for a +15v super regulator. Looking at the schematic at the Diyaudio store I calculated R6 from the formula R6 = (Vout*R7/Vref)-(R7+R16). So If R7 is 1k ohm as in the schematic and Vref is 6.9v then R6 = (15*1/6.9)-1.1 or a 1.07k ohm resistor. Does this look about right?
