This is an old six meter amp, a 4-1000A that I built for the June
VHF contest. Construction was started on May 21st and first QSO
was made on May 31st.
The box on back is an ICE low pass filter.
This is the underside of the 6M 4-1000A
This is an HF amp, it is single band with the pi-net on a
rack panel above the RF deck. I had pi-net panels for 160 and 10M
single band contests). Notice the third 4-1000A socket was
has a Dahl 75A xfmr and 3A plate choke.
