Remus diy tube preamp

[stenak]

I am going to build myself a Remus preamp. Have the original magazine, Audio/Video from around 1990? Built my first version around 1992-ish?, and it did not sound very nice at all. My skills are probably better now, compared for about 30 years ago? Found a new schematic at Lencoheaven

Looking at the schematic I see that the cathode resistor on V2 are 10K, but at the original schematic from about 1990, i think it was 2,2K? I know that the tapebuffer are removed from the new schematic. But why 10k and not 2,2k?

Perhaps he used worn out tubes? See what happens when negative grid voltage (relative to cathode) drops toward 0V:

10K seems high to me for a resistor in that position unless there is a DC feedback path that might be effectively lowering the value.
