I would be careful using vintage tubes for testing unknown ballasts. I would get a chinese test rat and use that instade of the vintage one.

I agree. I'd keep an Alto on hand for testing. A few years ago, I blew up a nice older (though not quite vintage) 22 watt circline lamp when I plugged it into a fluorescent adapter that turned out to have a shorted ballast.

Me too would use the crappest tube such as globe branded lamp from 99 cent store to test subject.
never know what a ballast can do.

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

I had already tested the ballast with an alto. this lamp was simply installed for this photograph. Since the ballast HAS tested out ok, I assume it is safe to run my vintage lamps on it now.. ALSO im debating on putting in a convenience outlet and I am definitely installing a switch..

I LOVE preheat fluorescent!  Preheat forever!!

I am actually surprised that design of ballast is quiet. The ones I have like that are noisier than the metal cased choke types. Glad it works well and I agree with the other members about using crap tubes to test lights initially. I blew up some good tubes with bad ballasts. I have blown up some good tubes in the past when testing old lights I had acquired.

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

When I rescued my vintage Sears shoplight with the .8A GE BonusLine ballast I tested it for the first time not with the 34w GE post-EPACT, pre 2003 34w Watt-Misers but with a pair of modern Sylvania Cool White Plus tubes. After that, however, I put in warm white GE MainLighters.
