Hi Bill. I run mine around 700w on rtty during contests without any problem. Been a rock solid performer for me. The highest temp it’s gotten to is 68C, then I back off a bit with the drive and TX, until it cools down to 60C. With lower output around 400w it stays around 55C-63C. There are 3 stages to the fan speed. It cools off quite fast.? I use 220v for my amp. It’s got many hard hours on it and very pleased with its performance.?
I don’t ever overdrive it. 50w max drive or 40amps max (appears on the panel).?
Panel is very useful for swr, power and temperature.?
It’s been a workhorse as I turn it on nearly every day for the past 5 years.?
Enjoy.?

I am currently considering the purchase of a LA-1k amplifier to support my Kenwood TL-921 which does not cover 6 Meter.
Can anyone provide me with any experience with the LA-1K and heavy duty cycle activities such as the Fldigi modes?
