[Amps] Fwd: Re: amp reading

[Alek Petkovic]

Probably quite true Carl.

I use a huge auto transformer here, with taps at minus 10 through to
minus 40 volts. The AL-1500 is permanently running at 230V AC with the
taps inside the amp set at 240V. Everything runs as it should and the
input voltage doesn't budge with the 'full 400" of RF out of the amp.
