brightness range video

see better link below. Not sure why I keep doing that (google sign in), thanks for fixing that for me SB.

Anyway I wanted to start with a video showing how my brightness pot works, will follow up with one showing pin voltages and HV regulation. The idea being to see how the range of voltages behaves on my set as a ref to what timmy is getting.

One of the points I was trying to make was there is only really about 1/4 turn of useful range. I finds some sets have better range, I think it has to do with how strong the CRT is. This one takes a couple minutes to get to the level seen in the video. This CRT wil have decent emission per the CRT tester BUT the cut off is just barely ok, I can just barely get it to the cut off line. Perhaps the lack of good cut off control limits the effective range of the brightness pot.
