Same experience here: K3 driving the KPA-500 on 220v to about 500w out with 23-26w drive, depending on band. When RTTY CQing, with reasonable period between CQs (like 3-4 seconds), amp temp gets up to 57-60c and the fan does its thing.
When I'm getting answers to every CQ, amp temp usually stays below 58c and lower when I'm S&Ping. If I'm fighting to keep a frequency and leave less time between CQs, amp temp will go up in high 60s but I then back off and have never gotten a HI TEMP warning. I find it to be a FB amp for medium power RTTY work.
