Folks,
It took me a lot of time to compile the Complete Data Sheet On The Most
Popular Russian Tubes. The data can be found on my site at
http://www.qsl.net/ut7ct (PA Tubes). The featured tubes are:
G series: G-811
GI series: GI-6B, GI-7B (70BT)
GS series: GS-23B (4CX1600), GS-31B, GS-35B (8877 ?), GS-36B (4CX400A)
GU series: GU-34B, GU-43B (4CX1000A), GU-74B (4CX800A), GU-78B, GU-84B,
GU-91B.
The information includes the complete mechanical and electrical data on
those tubes as well as graphic charts.
Please, do not forget that the mentioned tubes are available from me at
a very competitve price.
Regards, Anton Koval, UT7CT
