Gene, et. al Is it beyond the realm of possibility that some small tube company might be convinced to do a limited (Sylvania quality) run of 6JB6's and 6AH6's? If a hundred hams signed up to buy several sets each, would that be enough, I wonder?
Anyone know an exec/owner of a tube company?

I do know that he is a big fan of the R4C. Maybe he is a fan of the B-lins as well.. 73 Gene K1NR On Mon, 30 Apr 2012 14:08:07 -0400 "Steve Wedge" <[email protected]> wrote: > Yep - and I've found 6AH6's for $3 locally. > > I fully understand that there are a lot of folks who want to keep > their sets original.
