Almost every standard tv crt yoke is rated around 0.900 to 1.8mh which is the standard 15khz(cga) range
almost all the tri sync chassis on the market are rated at 0.300mh
you can put a dual sync chassis on a standard tv crt but not to my knowledge a tri sync

keeping the orig game monitor's yoke is the best bet.

basically, what is done in multisync computer monitors is switching in/out capcitance in the h sweep for the various freqs.

changing a modern crt really isn't that difficult .  just take your time, be careful and methodical...
there are some variations in cut off voltage - but, that usually isn't a problem.
and most will have identical pinouts for same size /type.


am a liitle familiar with the process.  ;)
over the years , have repaired many a tv ...
used to be an ASC for panasonic/quasar, sony, zenith/lg, rca

the oldest tv repaired to date was a 1948 zenith.  and a fun challenge it was !!  8)
