Hi folks , I recently saw an ad in ebay for a Russian priboi amplifier but since im having one pirboi myself I am kind of used by now to it's internal design but this one seems different and at output uses the 6P36C tubes instead of the more typical 6R3C-1 double tetrodes the original priboi uses.
if anyone here feels competent to comment on this subject please do I would like to find out this mystery device which I believe was some kind of an experimental version of the same priboi manufacturers.

To me this seems to use EL519 (=PL519, 6P45S), not 6P36S.
PL519 is high transconductance type with high Pa, so most propably works fine.

Ok maybe your right I have one 6P45C at my home it's kind of big.
What I wonder is whether this design was a factory made one or did someone made that himself , from the pictures looks like factory , but that feels strange as these I haven't seen that often at all.

If it were a factory designd why would they used western type tube when similar domestic 6P45S were available?
So I quess that it is some home made modification.

your right about the tube choice but I was looking more into the cirucit boards and other parts used and they do resemble Soviet era electronics.
Also I asked this question because when I saw this I recalled seeing exactly similar inside layout and parts on another priboi in some Russian audio forums.
can't be a coincidence.
in the USSR many factories were known for manufacturing a great model for tests and then realizing that it's better than the government want's it to be (in civil manufacturing of course) and then usually something couldn't be done like parts supplies and or all the paperwork and they went back to manufacturing to the typical models.
