I would check the EHT transformer to confirm it is working properly. Given the age of the speakers I am starting to see EHT transformers fail. They will still produce voltage but less than they should.
Normally the EHT transformer will produce voltage in the 600-650VAC range. When they fail the voltage will drop quite a bit , 300VAC is not uncommon.
If the transformer voltage is OK and the EHT board is working properly I would suspect excess leakage of one or more panels. This will pull down the voltage and the panels will not properly charge. They still play but with reduced output.
Best to check both the transformer and EHT board with the panels disconnected.
