Is the voltage drop across a vacume tube rectifier significantly higher

Yes, for the most part. But how much depends on the load.

Previous owner of my HX-50
changed over to SS. I am changing out capacitors and just curious.

Measure the supply voltages and compare with the schematic. If they
are all too high, add in a dropping resistor.

Derate all the capacitors anyway, though. They'll last longer before
the next replacement.
