Frank, On 80 meters into a dummy load on CW you should get around 140 watts when the ALC light just turns on.
As you go up in frequency the output will decrease. On 10 meters, you should get over 100 watts CW into a dummy load when the ALC light just starts to turn on. I wouldn't run any tests without a load. The protective circuits will reduce the output power to protect the final transistors. There has not been a lot of talk about replacing the PIN diodes on the 2nd IF / Audio board. They are still available. Good luck with the rig.
