Agree about JJ tubes...avoid...
Regarding the Russian output tubes, I have a new quad of Tung-Sol (Russian made) 7591A tubes. I had originally bought them for my 500-B but I think I will use them in my TA-800 instead. Since neither receiver is working (well, the 500-B sort of works but I don't want to press my luck before restoring it properly), I can't comment yet on how good, bad, or indifferent the Russian Tung-Sols are.
I do know that Soviet mil surplus 6П14П-EB tubes are great replacements for 7189 tubes. I think they sound just fine in my TA-600.
