I have a Hz function on my meter that I have measured 60Hz on a couple tubes, but I haven't checked it on all - that's a good point. On pins 2,3 off the CRT, the AC does jump around a little, and that's probably video signal added to the AC. I'll go back and verify on the sync and CRT what the freqs are. I find that easier than a scope.
