[Amps] Water cooled amp question

[Will Matney]

Joe,

I know some samll rual stations down in Kentucky that do still sign off. I'm not sure about how large they are power wise though. What I am thinking for any that would need this heater, they could add a threaded boss on each tank (after cutting ot a round hole behind it). Then use standard water heater elements screwed into the boss. Just wire them up with a thermostat. Cut them back to where they just keep the water from freezing up.

Best,

Will
