Kurt,

Thanks for the info. That sounds good to me unless anyone sees a problem
with this method. I checked my inventory and I don't have any 12BW4s. I
thought I would have a few around here.

I checked for subs for the 12BW4 on NJ4P's tube database website at
http://hereford.ampr.org/cgi-bin/tube. There are no subs for this tube. I
guess we should start hoarding them before the word gets out and they reach
the $35 price of 26Z5s.
