So I get a monitor to repair the other day from a friend. He's having me look at it for a friend of his. His friend bought the monitor from an op for cheap, The op told him it needed a new fly "or something". I finally get around to looking at it and notice that it's a
Kortek K1-2-VOA. But it's stuck on a 25" tube. Everything I can find on this chassis states it's for a 19" tube. For some reason I suspect that it has been hooked up and powered on and didn't work. I checked the yoke resistance and it is 27.4 Ohms on the vert and .9 on the horiz. It seems to be in between hi and low Z yokes. I would call it a high Z though. I hooked the ring tester up to it and the vert tested really low very close to the bad reading.
So I guess my question is, does anyone know what tube a K1-2-VOA chassis is supposed to drive and and is it possible for a yoke to be bad other than shorted or open?
I have quite a few chassis I could replace this with but I believe they are all for low impedance yokes. K7000, Pro Max, A-1 etc...
Is there a way to tell from the chassis what type of yoke it uses?
I have a couple Promax I think that have the values stated on the side but they are for low Z.
Anyone know?
