Yes, I should suspect that a lower freq for a high freq tube is no
problem... I think why you don't see them ever used at 144 Mhz is that
there used to be VERY expensive--you would only pay the money if
necessary and there were much cheaper alternatives for 144...

Warmest regards,

Hello, Has anyone tried using 2C39's for 144 Mhz? I happen to have a
few
of them and was considering using them for a junkbox amplifier for 2
meter
SSB. I have found several 1296 Mhz amps that use them, but so far,
nothing
for 2 meters.

Thanks.
