The Rega arm maybe likes the Nagaoka better for weight and compliance, or both carts work with same ease on the same arm?
C3, up to 100nF the most. Not part of riaa but part of very low frequency filtering, big value can give rumble with big speakers.
Buy Teflon FT-2 Russian caps, they are very influential in that position and of course much better than those you got. Laying out such huge caps in your present PCB is a bitter story though. K42-Y//FT-1 0.022uF can be a good more compact combination. Watch for not much woofer flapping with the bigger value C3 and disc eccentricity (wobble).
What are your amp and speakers? Level is enough in your room with those carts and this phono pre?

Down to earth system, not big speakers to bring much bad feedback to a non suspended turntable like the Rega. OK.
Would be a good idea to buy more 2SK170 GR as they are so cheap? I think is the last stock from Romania and is around 30eurocents/piece.
Here it is one recording I made with the simplistic. One of my favorite tracks to evaluate sound quality.My first recording from LP, so be gentle! look of love salas njfet 2sk170V.wav
I use BIB now from V1.2 and seems better, probably due to my layout on the V1.2. Set at 230mA dual mono CLC prefilter.
Teflon RIAA caps and interstage, mundorf silver in oil output, sinkoh and takman metal film resistors.
And some porn from the phono and from my cave!

Dusty Springfield who sang the track says you got a nice musical tone, one of the better files posted here, surely a nicely synergistic TT and a well executed simplistic, just be careful with those rest HV DIY gear when tampering.😀
The #26 pre and Baby Huey EL84 amp look purpose built, no frills, but very nicely put together non the less. The speakers, wow!

They can be very useful parts if you know how to fix for GR the many DIY circuits designed around BL IDSS range.
Thanks for your nice comments salas.
I am always very careful with HV. I use probes and stay away.
The Baby Huey is very nice. I like it better than F5 and Aleph J.
Did you ever try shorter XLR interconnects to Huey and longer speaker cables, i.e. inverse installation of that in the pictures?
*If you look at F5 and BH schematics there are enough similarities in approach beyond FET & Vacuum domains or BH's shunt feedback.
**gingertube was prowling the tube threads with an eye for revisiting Baby Huey recently by the way. Maybe he will have something up his sleeve in due time.

Unfortunately no. I do not have that long speaker cables now. These should be 7 meters minimum. Would you suggest to bring the Huey closer to the pre and leave the active cross and amp for the sub were they are now?
*One of the reasons I liked the baby huey.
**I am waiting for this, but something tells me that it' s going to be with a mosfet follower and would like to stay tube only on this.

You know, since the input 12AX7s on the Huey have a Miller and the many meters interconnect has a capacitance blah, blah, maybe bringing the Huey closer to the #26 pre could yield more performance. If you can do an easy rearrangement it would show. Just an idea.
Yes, I know. Total capacitance of my interconnects is around 700pF for the 7 meters. I could reduce the input resistance to 47K from 100K. Is there any influence for being in parallel with the 25K input resistance of the active cross?
Hi Salas,
i have built your phono stage to fet. For the riaa i have used:
Resistor metal film 1% 47K,
Resistor metal film 1% 6.8K,
N°2 Cap 47n + 1.5n to 5% (i measured 46500),
N°3 Cap 15n + 330p + 100p (i measured 15300).
This value are correctly for accurate riaa?
Many thanks
