Simplistic NJFET RIAA

[SGregory]

Initially it seemed to be a step back. The dynamics were compressed and the soundstage squeezed a little in the center. The sound was changing rapidly for the better as I listened to it. After an hour or so I was starting to notice that the dynamics were returning and the stage was opening up again. I would rather wait a little before I comment or commit. I figure the caps need a little time on them, particularly the 47uF electrolytic. I did notice that tonally the sound seemed to have more weight in the mids. Again lets let this burn in over the next day or so. I also want to watch the voltage drift. It is creeping on 43Volts right now.
For that Cap I bought two types to try. The one installed is the Vishay Sprague type 678D which list the impedance at 0.18 at 100kHz. I also have the FC ones as back-up.

Give it 48 hours. Also see its set to 45V after half an hour with the lid closed, not initially.

I will keep it in for a while. Your question made me throw an album on. One impression that I should have mentioned before is that it is absolute black. Utter, Total, Complete silence between the notes. It really brings out the ambience of the studio or hall the piece was recorded in.

[Salas]

With new electrolytics there is a reforming period. Also don't miss the opportunity to fit the FC which has the ESR I designed and tested around. Low noise is a very good sign non the less.

[SGregory]

The FC had a listed impedance of .35 which was at the top of your range. If it doesn't open up after a few days I will put in the FC.

I bought some of the vishay caps also for the LED bypass one the new preamp. That is going to breadboard soon.

[Salas]

It will show soon one way or another. No haste.

Welcome to V1.2R sound courtesy of Mr. Salas (thanks again Nick), did you use the same current in the reg like the V1.0 remote sense? BTW I use Pana FC for the 47uF lytic.

When you tap on things, there is no sound anywhere.

If you aren't in the heaven, you are very very near....

Don't bias the listener. 1.2R could be best to some of us unanimously by now, that does not mean that 1.2 can't be better in another system. All those regs will have an optimum system for synergy. Its fortunate there are three options.

Yes you are right (Its fortunate there are three options), I prefer V1.0 remote sense in my unbalanced phono & V1.2R in my balanced phono that's the reason that I asked SGregory his subjective opinion.
