Cathodyne phase splitter with CCS?

So the idea is it's more like a choke, acts like a resistor at DC, but with high impedance at audio freqs?

Yes! Like a very high quality choke, with low voltage drop, so B+ is needed much less than with a plate resistor. However, a real choke can swing voltage higher than B+.

Also, if to use P-type JFet like 2SJ74 with a diode in source for a voltage shift, feedback resistors may be selected of bigger value.

So, in the Jones circuit what is most going to give to permit this to work? Will the plate voltages change or the upper CCSes run in a non-linear region, for example and is it best compensated for at the grids or upper CCSes?

In my phono preamp, I have two stages that are directly coupled.

Have you made this public as I'd like to take a look if I could?

Not yet. Have patience. ;-)
