Don't do this!  There is a reason why they used that particular mechanism.
The current through the coil must be reduced *gradually* or else it might
wind up making matters worse (i.e. instead of a DEmagnetizer it would
become a magnetizer.)  It shouldn't be too hard to find a replacement
thermistor; just about all high-quality CRT's (and even TV sets) use
a similar mechanism.
