input tubes using 6922?

[jarthel]

i haven't seen a circuit that uses 6922 as input tubes. can someone tell me why?

thank you.

Because you haven't looked very hard? Start with the Marantz 9, 50 years ago.

They are VERY popular. you can also look for circuits that list: e88cc/ecc88, 6DJ8 etc (there is a Soviet variant that I can't remember off hand). They are all very similar.

They are everywhere!!!

i guess I wasn't very clear and I apologize for this.

I've been looking at 300B/211/845/2A3 circuits and I rarely see 6922 variants in such a circuit.

is there a reason for this?

Hi,
I think its because the gain (mu=35) is just a tat short for a 2-stage integrated amp even for 2A3, but its ok if you ave a low gain line stage.

I'd tried em as driver for my 2A3 briefly, Like it a lot.

Cheers

6H23pi (or transliterated 6N23P)

from here http://www.vacuumstate.com/schematics.htm 2 circuits that use 6922

The Soviet variant is 6N23P. Heater 6.3V 365mA.
6N23P-EV is the substitute for E88CC.
