Is this the bigger big big brother from the old miniature triode 6CW4 ?
We used the 6CW4 as a HF amplifier in the sixties, but only in VHF
receivers front end.
I just wonder what will be the prices of such a beast.
Are there yet caracteristics available ?
Hopefully this power tube can work on higher frequencies then 30Mc/s
Thanks for some more info.
