Hi
Even if it works now, the power supply caps are on borrowed time. There are not many parts in there I will wager. Just change the power supply caps and diodes and the coupling caps and it will probably run a long time. If you throw new tubes in there you are risking killing them when it fails. I don't have a schematic in front of me, but I bet it is cathode biased. If so, the cathode resistor value will probably need to be adjusted for modern wall voltage. Really, it is probably a simple rebuild and it will be reliable. Right now it is a bomb waiting to go off.......
good luck...
Don
