I did try my 7610 running about 50 watts into the L7 with a standard keying interface for Icom. It seems to work ok. I get about 500 watts out SSB with the CW position selected. Will try and run it that way for awhile and see if it is ok. Also I swapped out the newer 500zg tubes for my original 500z Penta tubes and they seem to be ok also.? I am happy with 500 watts if that is what I can get.
