selectivend 2a florescent light bulb size ?

[jtoenges]

I measured the distance between the faces of the receptacles of the florescent bulbs in a selectivend 2a.  One measures 14" the other measures 14 1/4".  This  doesn't count the bayonets that stick into the receptacles.  The starters are fs-2. Does anybody know what size bulb and wattage I should use?  If it is a 14" tube where can I buy them?  I just got the selectivend manual but couldn't find a size.  They refer to the light bulbs as "910523"  the ballast are listed as 15-15-20 watt.

I searched this site but couldn't find any info.
Thanks,
Buck

Welcome to the board Buck !!
On my SV's have just replaced the entire assembly with modern parts.
The originals may be out there but you need to think about future use and replacement costs.
I'm liking LED at the moment.
