I am pondering my next amp build - - a 5-bander (10 thru 20m) dedicated to
my 5-band beam with around 800 - 1000w output. All the better if I could
use my existing power supply that has 2500/2900v at 600mA (or so)
capability.
Looking for a tube suggestion. I'd prefer a single tube with good IMD
specs, that is easily obtained/replaceable/affordable.
By not having to design for lowband operation, are there some design
considerations or optimizations I should be aware of ? Bandswitch and
tapped tank coil vs. roller inductor? Vacuum vs air variables?
Thanks,
Steve KK7UV
