Hello and sorry you're having problems. How did you test the bulbs- simply visual inspection, or did you use a meter to test the filament?

Also, do you have a meter that can test DC volts so we can test the voltage going to the bulbs?

You would first want to use your meter and test for 8 volts at the lamp connections. If the voltage IS present, then you do indeed have bad lamps and they can be replaced at the link below:

If the 8 volts is not present, then I would consider retro-fitting a 9 volt power supply (putting a 5-10k dropping resistor in series with the positive) into the Sansui to power the lamps:
