I have acquired a homebrew amp as follows:
It has two 4-400s in parallel in grounded grid (with a hole for a third one,
FWIW). The bandswitch has positions 80-40-20-15. It has TWO 30A Filament
transformers with 110V primaries wired in series with the outputs in
parallel. Input is not tuned.
HV power supply is separate, outboard.
This seems like something I might have seen in an old handbook? Does it
ring a bell for anyone in this group?
Fun project. Any conjecture about how I would fare adding 160, 15 and 10
meters?
Thanks in advance for any posts in response.
