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.

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?
Thanks,
Mike M
