I will have both MC and MM correctors inside, with L-R correction.
This was going to be the next project I was looking at :-)
A friend has offered to sell me his phono. ;-)

Here is chematic of power supply for filaments of phono stage tubes, It has to be very clean and separated, because 6S7K-V tubes have filaments connected to cathodes.

Interesting power supply for the 6S7K-V. Could you let us know what the active devices are.

I've been playing around with some 6S7K-Vs in a line stage, basically the Eric Barbour version with no cathode resistor. So far I like what I hear.

Perhaps this tube deserves its own thread.

Hi Ray;

In this stabilizer I am going to use 2SK1388 MOSFETs and 2N3702 BJT.

I rectify 12.6 to get clean 6.3V for filaments.

Do you have a part number for the adjustable 2.2 ohm resistor or do you just use a 5 ohm variable pot?

What is the purpose of the 1K resistor in parallel?
