[...] > Regards > Paul Paul, When you say lamp voltage, what are you measuring? I have the LPRO repair guide by Fred de Vries. It doesn't say much about the lamp voltage except it appears on pin 5, and a healthy unit measures 6 to 9 volts. There are some schematics that appear to come from a patent, but I couldn't find any reference to pin 5. http://www.radcomms.net/EFRATOM%20LPRO%20101%20Repair%20Guide.pdf So what does this voltage do in the circuit? Is there a way to measure a similar voltage on a FE-5650A or FE-5680A?
