Do you have the schematics? Do you know the test target for the tube? Ie NNN volts at XX amps?
Small frame argon 101.
Start at 3/4s of rated current. In current, not light mode. If its stable, leave it run for at least a hour.
If you have a ampclamp, put it around one of the cathode leads and watch Delta T on the cathode, increasing cathode current soon after she starts is a good thing, it means the pressure is correct in the tube.
My buddy has two of those with dead psus, that is why I'm asking about the schematics.
Its a ballasted tube, so there is nothing to adjust. I would run some CLR in warm water through it to remove any deposits in the magnet.
