[Amps] GS23B Plate load resistance for HF

[Alex Gavva]

Dave and All,
GS23b is the greatest Russian tube, it is not so known as GS35b, GU74b 
or GU84b due to its socket, it is impossibly
to find industrial ones and it is very hard to build GS23b quality socket.
These tubes were wisely used in TV TXes on 400-600MHz, my friends , who 
worked there told  that these tubes easy worked 1.5-2 years there
in cont, regime of course.
Russian hams used these tubes on HF exeptionally rare, they had many 
other tubes with ready sockets ( GU43b, for example).
More info abt GS23b efficiency  on 2m, 70 cm and 23cm you can find 
here:  http://www.nd2x.net/base-1.html
Mats, KD5FZX  built 1kW 23cm PA with GS23b, but only 1 pcs form 5or 6pcs 
was able do it.
