The size and weight factors get more and more important as you get
older. Luv my KPA500 and may opt for the KPA 1500 for use on AM.

Only $10k and possibly a visit from the FCC!
I had a factory built Heathkit Chippewa KL-1 amplifier back in 1965. A
pair of grid driven 4-400 tetrodes in Class AB1. 10 watt drive for 1KW
plus, plus out. 3-400Z triodes didn't enter the picture until 5 or 6
years later. The amp weighed 90lbs
