Thermofax Woes

The light bulb burned out on my thermofax machine this afternoon, I've been doing some reading since then nad have discovered that my machine is 1. much older and 2. the light bulb for this machine is not that common!  If you have a thermofax machine you need to check the amps/volts before you purchase your bulb the bulb for the 12 amp 115 volt machine will NOT work in my machine!  Onward searching I go!
