If anyone here is a ham (DE K2KD), you may appreciate that when I first got into amateur radio in the early 90s, a restored Heathkit SB-200 linear amp was like the gold mine of gold mines. It cost about $500 (+ tubes) and would get your “standard” HF rig from 100 watts up to 1200+ watts, which was life-changing. It was about half the cost of modern amps at the time, and I always loved that a solid piece of 1960s engineering remained a staple on the desks of even the most techno-centric hams.
