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.

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.
