Thanks Russ! I have observed this myself, but being a 'radio packrat' I don't throw tubes away. Some pretty weak ones still sound decent enough, and since there will be "no more" of most of our old radio tubes, I sure dont want to see any usable tubes trashed. I don't notice this as much on the Precise 111 since it uses separate filament and power transformers but note it more on the Hickok 600a and my old Eico. I really appreciate your input Icon_thumbup
