I've been searching the forum and have come across some great information. I need a new, "unburned" tube for my Missile Command. Any tube is ok for the first 8 waves, but once you hit the bright blue background...the burn, any burn, is extremely annoying. And forget playing Super Missile Attack as the 2nd screen requires a clean tube.
So I tried a new monitor ... lets not get into that though... I've moved on...
I'm now reading up and my best choice is to swap a tube into one of the old monitors I have (I have a few G07s, WG4600 and a few others..all with nasty screenburn). So, reading up on things (and a special thanks to Orion3311 for his site and tube swap writeup... just missing the yoke swap..which I think I'll most likely need to know) ...I notice he mentions on one of his donor tubes, that a Panasonic CT-9010 tube is an exact match to a G07 except the ohms are about double the value of a G07. The suggestion is to use a 50 ohm resistor in parallel across the vertical wires to bring it into acceptable levels.
I'm just curious, if this does indeed work, couldn't we adjust almost any low impedance tube to fit a low impedance chassis (and high for high) provided we can come up with an appropriate resistance? This assuming that the resistance level of the donor tube is higher than the original and can be adjusted down.
for reference, when I say tube, I'm probably referring to the yoke..not the tube itself
I'm still learning...
Also, if the ohms are the same, what happens when you match up a 20" tube with a 19" chassis? just curious. My guess is that you'll have a black border around the screen.
Thanks
