It works. Need some wiring organized and should be good.

Looking at that picture and zooming in to those dip switches, nothing is switched "on". 😕

 

[yuradams]

How to setup those dip switches? I have pickering xv-15 which has 47kohm load impedance as per spec. Should it match?

 

[JoeAlders]

My experience is to simply use your ears while experimenting with the value of the load resistor. I am using an ortofon 2M Red cartridge and decided to
use the 47k load as best for my 2M Red after some listening sessions. Ortofon also recommends a 150pF load capacitor in parallel with the 47k (for the 2M Red), but I have omitted that capacitor. After I finished experimenting, I removed those dip switches and simply soldered a jumper wire between the 47k and the input.
Just my two cents of info.🙂

Just select the no 3 position on both the dip switches for 47K loading.

Hi Sachin,
I'm interested in both kits phono and psu, without cases if possible. Are they still available?

Here is my CNC phono preamp I recently built into a chassis with a volume control and input selector. I built it to match a sweeptube amp I built a few years ago.
I've never felt a need for an active preamp with this amp. I started out just building a passi e preamp with a selector. Then I rememberd I had a Pyle phono preamp I bought to use temporarily and was going to put it into the chassis. But decided to uild something better and went with the CNC. A.few days ago I disconnected one pair of the inputs from the selector and wired them right off the output of the phono preamp. This way, I fan use it as a stand alone phono preamp if I wish.
I've been pretty happy with the CNC preamp.

Nice build.

Thanks, it turned out great. Thanks again for all your help!

Cheers

Would be interested in the MC phono stage and matching PS pcbs.

Hi
MC Phonostage PCBs are on order. It will be available after 10-12 days. I have the power supply PCBs. Let me know if you can wait.

I can wait. No rush

I just finished an active subsonic filter to match this setup using the CNC phono stage.
