That's your home-brew rig, isn't it?

Thordarson CHT-300

That rig is actually an "evolved" Viking One. When the internal modulation transformer shorted, I stripped it down to a simple RF deck and replaced the 4D32 with three 6146B final tubes running at up to 750 VDC. I use a separate modulator deck built up with a pair of 811a's running at up to 1500 VDC into a Thordarson CHT-300 watt multi-match transformer.

The Viking used to reside in a 6 foot rack next to the homebrew transmitter, but it was really under-utilized in the basement. So, over the past month I rebuilt it into a smaller rack and moved it upstairs to the more frequently used station. My wife's only comment was, "Is that going to be staying there?"

Above is a picture of the modulation deck as it was being rebuilt.

Cool! I thought the knobs and VFO dial had a familiar look to them.....
