[Amps] gu-84b cathode driven

[bubba willis]

i was wondering if anyone knows of anyoen using a gu-84b in a cathode driven
"grounded grid" configuration. i have heard that these tubes would not stand
up to this like the tougher 4-400 and 4-1000 tubes. if it is the high
current in the control grid that is the biggest problem. would "floating"
above ground with 10 ohm resistors or multiples of resistors to get to
around 10 ohms help?

just wondering.
