tube line preamplifier circuit

[Gost22]

The weaknesses of the Gost22-favoured design were pointed out in this thread.

Hi
I wonder if the 1/2 tube 6DJ8 I would use as a buffer, then the output impedance will be around Zout=600ohm!😉😛

That is a bit better, although hardly 'high-end'. Who owns the copyright?

Not my work, but some changes may be High-End!

I have the Pete Millett Low Mu preamp and I think it is one of the best sounding preamps I've ever heard. I took it to an audio meeting last year and everyone there said the same. The only thing I had to do differently was to use a separate transformer for the heaters as the transformer Pete calls for does not have enough amps on the heater windings.

I only have one in and out on mine.
