The SB-220 DESIGN specs are as I indicated. Look them up.

I wasn't aware National Radio serviced SB-220's, and sold and
serviced 3-500 amps. How many ground grid amps did National sell
and service with grids floated by capacitors to people with solid
state rigs?

I suspect they are very different, since gas is desirable in a Toro

Look at a person who keeps keeps starting and stopping a
business every few years under different names leaving people and
banks stuck with debt, and you'll probably find someone who puts
today's profits over tomorrow's business.

I prefer engineering texts or experiments to education by cartoons.
