If the tubes and Dial lights don't light, you may have a bad power transformer, so take one of the tubes out and apply a voltmeter to pin 8 to see if you have voltage, then you should look at the wiring for wires in the wrong hookup or a broken wire in the 6 volt line.

If the clock runs, then the fuse (3amp) is O.K.

beautiful shape.  Have some documentation.   The clock is running, but the tubes do not light up.   Is there an easy fix or check for this?  My expertise is mechanical, not component level, though i have be lucky a few times.  thanks.
