Great Video, Would be interesting to see high power tube amps for P.A systems around 1KW mono blocks e.g. for reggae & techno sound systems etc i have seen 400 watt amps made using up to 24 KT88 type but way too expensive to replace the valves every year also hard to find designs and transformers for this much power...

This was a very cool video! Thanks for sharing it with us. Well it looks like the Russians not only make very cool looking spacecraft but they make cool looking tubes as well. I like the RMH 90! :-) Respect from Apache Junction, Arizona.

all that is soviet military tubes ,my self still believe in good old Eimac,due to low inter modulation characteristic and predictable behavior...mostly use pair of 4CX1500B..tetrode,with third order IMD -55db ...that old rusky tubes are gassy,and hard to find 2 or more tubes with same parameters...only good one used by myself is GS35B...but that russian tubes cant be beaten by price,and everybody used them cuz of that,even US amateurs...

Awsome Linears! At 4:41 and 6:03, you show a external anode tube being cooled without a chimney--I did not know that could be done. Does that work good? And at 6:20, are those tube similar to 833A?
