This has been an interesting thread. Along the same lines.....I wonder why
someone doesn't offer a well engineered kit amplifier? Basically a
modernized SB-220 possibly using different tubes? Is there possibly some
FCC regulation preventing this??
Maybe two models, a KW class and a legal-limit class. Perhaps even a solid
state AMP.
The kit amplifier would be able to purchase components in volume, keeping
the cost down.
Anyone know how many amps Heathkit sold anyway?? I'll bet it was a lot.
