Yoke readings close enough for chassis testing?

I have a K7203 chassis I need to test, and I thought I had a 7203 tube around here, but I can't find it.

I know the K7203 yoke readings should be:

Horizontal (red and blue) - 2.1 ohms
Vertical (yellow and green) - 15.8 ohms

I have some K7000 tubes with yoke readings of:

Horizontal (red and blue) - 2.9 ohms
Vertical (yellow and green) - 13.1 ohms

Think that's close enough to test the chassis with?
 
id be a little worried about the vert...

to be safe, you could add one or two one ohm high watt resistors in series with the vert..

i di dthis before when i was testing a nanao chassis on a old tv tube anbd yoke.. added the resistors untill ohm reading was ok, worked but didnt fit the full screen of course..

but it would allow you to fire up th chassis and make sure all the colors work etc
