I'm selling the following:

QTY 4 :  2" Diameter Corona Balls (1/4-20 Thread)

I'll sell them either 2 for $20.00 or the whole lot for $30.00

These are hollow aluminum corona balls and would be great for either a
safety gap set-up or for capping those high voltage
power supplies and capacitors to reduce corona.
