##  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 
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 
load caps.   Ok, with 6 x vac relays,  they end up with enough combinations 
any C you want.  Thats one helluva expensive way to do it.  They look like 6 x 
G2 relays. 

##  JA6TAY  does that quite often on his myriad of different amps, but not
