got this tube for $3 from an auction...its a 8 pin....horizontal = 3.4 vertical 16.1.....can i use this for a k7203 chassis i have? the neck is long a skinny compared to a cr23
That tube will work fine, just make sure to mark the conv rings so you put them back in the same spot. Try to use the TV yoke and if it works great! I have a bunch of those tubes with almost the same ohm yoke and I never got them to work so I just used the 7000 yoke instead.
