EICO 320 Signal Generator

I am curious about the gold thing (diode I assume) connected to your line cord. Is this replacing the old? What did you use?

Thanks to everybody for the nice comments.

The gold thing is a dropping resistor to bring the line voltage down to 115Vac from 120vac.  I'm not sure it is really needed, but I'd rather err on the safe side.  There was no resistor before.

BTW, since there pictures were taken, I've added the extra trimmer caps (which takes it from a 320 to a 322) for each coil which made the dial more accurate, but I use a frequency counter with all my signal generators.
