The GS-35B will run for ever at 4KV with no problems. I have built dozens of
amps for VHF and UHF using this tube and running 4KV+ on the anode.

REPLY:
The original post asked for a tube that will run at 3.8 kV.... the max spec
for
the GS-35b is 3.0 kVDC. Don't be fooled by the "instantaneous value" spec of
6.0kV. In normal operation the instantaneous anode voltage will swing from
aprox
zero to 2X the DC supply. If your DC supply is 3.8 kV, you will be exceeding
the
instantaneous rating.
