[Amps] Question about ampifiers

[Gary Schafer]

Hi Carlos,

If you are getting your power from a 3 phase line, and you have 120 
volts then there should be only 208 volts across the two phases. I ran 
into that problem at a military installation I was at one time. There 
was no 240 volts to be had. Only 120 and 208 or 3 phase. The amp would 
not work well on the 208.

The AL80B has the 220v option but the Heathkits just work with 240v. There is a drop in the line voltage and my amplifiers are not working at their full potential.
