6N23P, 6S19P anybody knows?

[lineup]

hi.

anybody knows these tubes? 6N23P, 6S19P
are there any equivalent replacement tubes?

is about one OTL Headphone amplifier circuit using 230 Volt supply
V1 = 6N23P .... V2,V3 = 6S19P

see attachment

6H23pi is considered a 6922.

yeah, thanks,
I did figure this out 6922, E88CC, 6DJ8

the others = output stage tubes I have never heard of
anybody?

by the way, i found that schematic at one russian site

6S19P = apr. ED8000 /tubedepot.com/

6S19P is something like one section of a 6080/6AS7/6N13P.

The 6S19P is similar to the American 7233, which is not cheap or common even here in America. The pinout is different. The 6S19P is common on Ebay. I got a box full from the Ukraine for $3 each. It is probably close enough to 1 section of a 6AS7 that a 6AS7 could be made to work.

thanks for all information
i think now, i will be able to find a similar tube
if i go for this headphone OTL ( Output Transformer Less ) amplifier

there will be a way.
if not find ABSOLUTE equal tubes for output,
will probably be possible to alter resistors in output

Is it two Tubes SRPP output?
.. unless I am mistaken

if looking at my schematic, in first post

Wouldn't it be possible to use 6H30pi in the output PUSH-PULL?

Of course, but You must make fase-invertor befor PP 6N30P /or selfinvertor - I have this one/.
