Well its 2009 and I went back to Tulsa and retrieved my HB transmitter and other gear. I currently have all of the racks pulled out and I'm slowly cleaning them, etc. The HV plate transformers/supplies mounted in the bottom of the 7' Bud cabinet accumulated about 2 inches of dust over the past 9 years, yuk! Attached are photos of the RF deck along with the screen and grid supply rack.
The RF deck uses and single 4-400CG (carbon graphite) tube, which runs much hotter than a straight 4-400A etc. It also has the B&W 850 pi-network band switching inductor, which includes 160m.
The modulator consists of a pair of 810's in push-pull configuration. The majority of the plate and bias supplies including the mod transformer were built per my specs by Peter Dahl about 11 years ago. I'll post some more info and pics when I get to the audio and modulator racks.
Happy New Year to all
