Multisyncs can be fun, I would give tutorials to the test guys (post manufacture) showing how they worked and what to look for if they don't work. I think it was a little easier for us tecknight as these were our designs so knew them inside out.

Design is fun too, two things stick in my mind. With the multisync concept be careful with a low line rate should the HT remain the same = very high voltages and usually something went boom. Well fizz boom actually.

A design engineer was measuring beam current using a rather crude but effective method (I'll spare you the full details) except his natural reaction was to grab hold of the ammeter to change the range - he forgot it was at 25kV - yes not a pretty sight, he survived but a really nasty experience.
