I've successfully reduced width with a few turns of wire on a ferrite rod in series with the H scan coils. The sleeve mentioned in the previous post is normally used to correct H linearity rather than reduce width.
The AW53-80 has a 6.3V 300mA heater. The suggested replacement has a 600mA heater. If the set has a series heater chain you will need a small 6.3V transformer to run the heater.
