First thing would be to read the high voltage on some other device. The problem could be the dropping resistor(s) on the meter. If it is low and does wiggle, then next measure the AC.

Very unlikely to be the caps or diodes.

The plate voltage on my MLA-2500 amp has always been rock steady. It has a
dedicated 220v line ran to it. The plate voltage has always been 2400v as
read on the panel meter....
After powering on the amp the other day this is what I get...Time to replace
the caps and rectifier diodes? They are original.
