Generally when there is an output difference it would be a bum EHT board. But you have new ones and it is unlikely they have failed. It is possible. Do you have a high voltage probe?
The shift in value up on the carbon comp resistors is not the issue. Most likely the other transformer resistor values are in the same range.
The tweeter panels hold up well over time provided they are not arc'd.
If the bass panels are original I would expect some excessive leakage pulling down the supply voltage. Do you hear any odd noises coming from the bass panels?
