Learning How to Test Tubes with Sencore - A Few Questions
Okay, I've always been intimidated to start looking into the technical stuff, but tonight I've set out with the goal of testing a few CRTs that I've had for a while.
I have a Sencore CR7000 and I've already put it through a field test. Everything looked good except that the filament voltage could be more accurate, but I can use a multimeter to make sure that's where I want it for now.
I would like to test the tube in a BVM, but first I was going to do a couple of much cheaper TVs. I started with an old Panasonic Quintrix. The first issue I ran into was the labeling of the pins. Everything is fine except for the filament. There is no F1 and F2, just H and H. How do I know which one is F1 and F2 or does it matter?
I hoped the book would clear this up for me, but the numbers it gives for the pins do not match the ones on the neckboard. It even has a pin 10 and there is no pin 10 on this tube. Am I reading something wrong? If I can't trust the book to be right about the pins, should I trust it to be right about the settings for voltage and bias? I'd be particularly nervous of using the wrong settings when connecting to the BVM tube.
