The voltage specs are for a PRIMARY input voltage of 115 volt, so use your variac to crank down the A/C line voltage when measuring the secondaries. Pulling the rectifier effectively "disconnects" the HV secondary from the rest of the set. With todays hi-z meters, and even with 115 volts on the primary, you will read higher than the spec voltage, due to no loading.

Souns like you have shorted filter caps, or a short on the B+ line or a ruined transformer that got that way due to the set running with the bad caps too long before you re-capped it.
