Philco model 77

So I moved the tubes around and those voltages don't change they stay at that socket, they don't move with the tubes. Now when I check the voltages from pins 1 or 4 to pin 3 I get -33vdc. (Same -33 on both tubes) As far as the power supply I've only changed one electrolytic there. That area has been worked on before and I don't know what they did or why they did it. Maybe they made a mess of it.
