Not at all.
It helps thinking of troubleshooting as a detective or mystery story. Not everyone is into those types of stories I suppose. It takes a while to figure out what is really going on. You have to put the clues together. Sometimes there are red herrings.
Really good that the power supplies are right. Many of the voltages depend on the current draw on them because they come through resistors. The voltages being correct means there are no major cases of the currents being off.
However you have to get the facts right. I think (hope) you got the CRT pins mixed up. Pin 1 and 12 should be at 150V, pin 10 should be more like 330V (that is from the boost voltage), pin 11 could be anywhere from 37 to 225V depending on the brightness control setting.
CRT pin 2 and V105 (12AU7) pin 6 should be 70V. There is a low DC resistance connecting them so the voltages should be about the same.
V105 pin 8 is connected to -85V through a 47 ohm resistor so that voltage will have to be about the same even if the current is very high. If V105 pin 8 was connected to pin 6 there would be a battle of the voltages (150V being the other) across R124 and R125 that could result in the -38V.
V105 could have a cathode to plate short or there could be a short between pin 6 and 8 on the socket.
