The yokes are totally different. The 7400 does not use an isolation transformer whereas the other one does need one. Power connectors are also different.

Can you use a 25" board chassis on a 27" monitor? Sorry, im not the brightest at this.

If a chassis designed for a 25" tube is used on a 27" tube the picture will be smaller and there may be "pincushion" problems due to the larger tube and wider angle of the tube design.
