The start up buzz is not as worrisome to me as last night when out of the blue everything got very distorted and fuzzed out, etc. And only came back normal after removing the tubes and reseating them twice.
I will wait and see what Woo says, or AA, and go from there
...
Thanks for the suggestions and input. I wish I had some other tubes to switch in and try out. Depending on how it all goes I may just pick up some NOS for those two tubes as well.
