[Milsurplus] Low B+ receiver operation

[Hue Miller]

Dave Stinson broke new ground when he reported on low B+ operation of 
Command Set receivers to spare having to change out many of the 
capacitors. Something that occurred to me recently, if you lower the B+ to
a fraction of the original B+, say as Dave did from 250 down to 65, will the
receiver exhibit a tighter IF bandpass, due to higher tube plate resistance
in parallel with it? Right now i am thinking "yes, it will", but i am also thinking
it probaby would not be a radical enuff improvement of great benefit to 
operation. Maybe if you got down to a really low voltage, like 12 volts on the
plate. On the other hand, there probably is the limiting factor of the Q of the
coils themselves.
