## You can no doubt buy it without the tube...or the entire B+ supply.
Henry offered those options on their 8k- Ultra. The part that baffles me is
their
use of fixed C for the C2 load cap. How does that even work ? All he has
is a variable tune cap, and a roller coil....and a mess of vac relay switched
fixed
load caps. Ok, with 6 x vac relays, they end up with enough combinations
obtain
any C you want. Thats one helluva expensive way to do it. They look like 6 x
gigavac
G2 relays.
## JA6TAY does that quite often on his myriad of different amps, but not
always.
