Default Re: Siemens MU 1600 Repair Suggestions

The resistor limits the current flowing through the neon.

Looking on the internet, the recommended value appears to be 100k for a 110V supply and 220k for a 230V supply. The eBay suggestion conflicts with this as does the resistor originally fitted.

You could try a 220k first and if necessary reduce first to 150k, then to 100k.
