These are a little better price...

Thanks Diesel.
That is a good price.

But is this a preheat ballast?

Which preheat ballasts are the best for double normal 40 watt bulb service?
I just bought a 1973 NOS GE double 40 watt preheat ballast on E bay.
GEs seem to give good service in the past.
I would like to stay away from dripping tar and smoke if I can.

Also the quieter the better.
I don't mind a little hum, but I am not in to growling.

Thanks
