Seeking solid state exciter/driver circuit for 5763 tube
 

I think the 5763 tube requires 0.1W class C RF drive for full output.

Can anyone point me please to any solid state HF RF drivers that would
be handy for driving this tube? Possibly with digital readout. I don't
have recent radio handbooks. Thanks.

Oh, I am thinking CW. Not an SSB RF exciter.

Hi, one now already somewhat "museum age" design was once described in
VHF Communication magazine 1/1982, A Wideband driver for the Shortwave
bands, if available... Still useful and solid desing.
There could be other equal designs somewhere with modern wideband
op-amps etc. but this would give HF range gain of 44dB and is linear,
not in C-class but can set to run in class C...
It will also drive tube amplifiers nicely with 1:4 step-up transformer
at tube grid...
This is not really a kit, but could give some new views to your needs.

Hi.

I've just got the RSGB handbook from 1973. Possibly a little old in the
tooth.

I could do with the latest RSGB edition, ARRL handbook, or some sort of
cook-book. Probably. :c)

There are probably some wideband designs or otherwise on the WWW. Just a
matter of finding them.

Maybe I should spend some money on a new book. :c)

I would think most VFOs could do this with the proper impedance
matching.My friend did something like this and either used a 4:1 or
16:1 stepup transformer to drive the tube. I think he used an HP
signal generator at one time to drive the circuit which was a 5763
driving a 6146B.
