list of tubes compatible with the CH-288 29'' chassis?

I can't find one online, trying to pair up some tubes with a working chassis.

A68PNT18X
a68kzn696x
a68aeg25x03

I have all access to all three of these right now.

I think the 18x will work, just need someone's confirmation.

Get/borrow an LCR meter (inductance/capacitance/resistance). Measure the H and V yoke resistance and inductance of the tubes and compare against stated values for the 288. If the tube's V value is within a couple Ohms/Henries and the H is within a few tenths of an Ohm/Henry, then it will likely be a match. I've done this before if you need help.
