If you have any doubts, just replace them...

Be careful. The Zanen get well kit for the Amplifone isn't
that great. It just has caps and deflection transistors, and your
problems aren't necessarily the symptoms of bad deflection transistors.
Also, there are some caps on the HV board that should be
"low-ESR" caps, but the Zanen kit just has normal caps. These caps
are documented in Gregg Woodcock's XY repair FAQ.
All the caps that come in the Zanen kit for the deflection
board should be OK.
