zenith: Zenith H664 Light Bulb

Does anyone know the specifications (or can read the schematics) for the dial bulb of this model?  I have the burned out one on hand, but it has no specs written on it and the parts list in the schematics only calls it PL-1.  It's a bayonet style.

Thanks!

Hi Craig.

A  #47 lamp is what you need.  The data sheet for the 35W4 explains how the filament tap on the tube works, and I would recommend checking out the data sheet as it is good reading material.
Happy New Year,

Howard

Thanks Howard.  I didn't know that this information was available, but it's right there in the document, as you noted.  I also have a better understanding of tubes and the values now.  Definitely worth taking a look at for relative newbies like me.
