Salas thanks, I will try later with 300pF
Here is with your walues:

I will investegate the "rolloff". My ears are not able to hear the difference anyway. I think channel balance is more important.
The AT-OC10 was new 25 years ago and I have not used it much, so it should be to spec.

If the voltage divider on the gen output sees many pF from test cabling it may weaken its signal level at HF on 220R load. Its a heavy load. Measure on 47K load too.
Can i use Clarity Cap CMR 2.7uF for C4, 2.2uF CMR is sold out everywhere, i wonder why 😉
Sometimes the size of the outputcap works as a rumblefilter ? Initial sound from the phonostage is very good, i will leave it powered for the next week. C3=Miflex C4= Auricap XO

You may use 2.7uF-3.3uF but watch the dimensions are still fitting the board. What is the value of the Auricap XO?
The Auricap = 2.2uF, do you like them ? The CMR 2.7uF has the same size as the 2.2, i'm going to buy that one.
Yes, i will do that hear how it changes over time. It's nice to hear that my Xono clone does also well compared to the UFSP. The Xono has 6 BIB's, 4 for the MM stage and 2 for the PREPRE. But it sounds thicker and is not so quiet.
That's a very famous bigger complex design you are listening with plus its hot-rod so it seems like a good start for the small guy UFSP.

Salas Hi,
Connected up once more and it was clearly a measurement error. I might have increased the generator signal a little this time, but the cables where the same. Input load was still 220R:

C3
I was just curious if anybody has tried both the Clarity CMR and Mundorf silver- gold-oil caps for C3 and what your observations/comparisons of the two are.
Thanks,
Don

Hi, can you upload it directly here because the link leads nowhere for some reason? Press go advanced for reply and there is an attachments menu.
