So how do they compare with the 6NIP, are they the same or what.
I have found the 6NIP to be exactly what you discribe over the 6922s.
Follow Ups:
The Russian 6N23P is a clone of the E88CC/6922.What is sold as '6922' by Sovtek is a 6N23P.
There are different flavours of the 6N23P, depending on the factory.
I anticipate the now-sold 'Sovtek' 6N23Ps are old production 6N23Ps,
whilst many of the 'Sovtek' 6922s are current or recent production
6N23P(-E/EV)s.All relevant electrical data are equal.
The 6N1P ist a completely different thing - its mu is roughly equal
to the 6922/6N23P, but the gm is two to three times smaller, so the
Rp is bigger, and it usually operates at higher anode voltage. As well, the heater curret ist _twice_ the heater current oft the 6922.It was foreseen for pulse operation, not for low noise RF applications, like the 6922...
