I could save you all the irritation if only my meters could read Henrys, but I guess it'd be nice to get it out there regardless:
I found this lamp at Goodwill, thought it'd look great hanging in the middle of my bedroom; very dungeon-ish. It has spent the bulk of its life as a bug-zapper, so it had this socket that accepted only 15-watt-florescent bulbs. Maybe a little too spartan. So I ripped out the guts (and that cruel little fence) and installed an E27 Edison socket (how many things have we named after him? How many things did he name after himself?).
I had a few transformers left over, and one of them, sporting two leads, was in series on the hot side of the bulb-- it was labeled “Listed Ballast 140 H”. My meter can pull off an Ohms reading if going downhill with a breeze and it said the ballast had 26 Ohms of resistance. It looks about the right size, I can see the E-I lamination-- is this something I could use as a choke for a tube power supply?
I couldn't find the part number and reactive ballasts for florescents are described as inductors.
I'm planning on getting my very own meter-that-can-do-stuff, but off the top of anyone's heads, is this something that would work?
The thing I'm working on now doesn't take much current; I'm not expecting to run a console off something that was ballast for a 15-watt bulb, but, eh? Maybe I'm just excitable. Yea, free choke, didn't have to wade through a HAM fest (though I wouldn't mind doing that right now).
I guess while I'm on the topic, does anyone know of a HAM fest-ish thing going on in Las Vegas, NV?
Thanks!
