[CQ-Contest] MLA-2500 as a contest amp?

[Roger Parsons]

Well I use two of them - both with QSK and other
changes - one modified with a single 3CX800A7 tube. I
keep the power down to about 1kW out and they seem
just fine. I have my grave doubts about whether they
would last 48 hours of full output though - I don't
think that the power supply, cooling and general
construction are up to it. Their owner can't last
anything like 48 hours at full output either. But
having two amps is a kind of poor man's auto tune!
