Adam, go ahead! All of these modern tubes have such short elements that it
is no problem whatsoever. In th especific case of the Gi7b, I operate one on
144MHz lying down without any problems even at 100% duty cycle for FSK441 or
JT65

Subject: [Amps] Operating position for ex-Soviet triodes?
Dear AMPS contributors,
Following some of the 'lore' with cathode and grid 'droop'
surrounding some of the ex-soviet triodes, is there any problem with
operating, say, a GI-7B external anode triode on it's side - does it suffer
the same malady?
I'd like to make a reduced height amp assy with a couple of these
'tubes' mounted horizontally. However if they suffer this problem alongside
some of the others, that's life, and it's back to the drawing board - your
input is appreciated...
Thanks for your time and for reading this message.
73
Adam
