They are quite big, as you can imagine for a 450V cap at 4,700uF.
Not very practical, unless it's for a high voltage circuit.
Mmmmm...
Gotta look for a trash bin with some tubes.

Its not a great picture, it was taken for messy lab thread. Look under the table, the box right behind the 20kV cap says In Touch.

Granted, the 450V is a little much, but talk about headroom!!!

If you ever do find the tube dumpster, I will gladly cede my claim of "bets dumpster dive ever," but only if you share!

Damn, I though that was an old radiator at first!!! You better strap those leads or you will kill yourself if it ever builds up a charge. But what a find!!!

Tweeker,

Was is the cool machine with the synched vacuum spindles for? ...Fusing glassware?

The table is a home made CNC machine, the spindles have been used for making whirlygigs for the most part. Picture with lots of 2 litre and popcan whirlygigs. They get suspended on a magnetic bearing and spin in the wind.

Safety first, a strap is a good idea. Though its been over a decade since that cap has had a charge on it. Oil caps arent as bad about that as electrolytics.

In the second round of cleanup, one of the labs in my building tossed some more obsolete junk, and I ended up with some more goodies, the gem of which was a 120VCT Bigassed transformer. I am not sure what the amperage rating is on it yet, but it is quite large. I'll post pics later, but I am hoping that with a regulator on it I can use it with some LM4072's I have in the mail. We'll see. . . .

Holy ****

Is that huge cir board a experiementers board or ??

Looks like those with copper rings around the holes

holly ****,those are for free

I want some

As promised, here are pics of the "new" transformer.

As for what the first round with all of the caps was, I think it was the primary power supply for a home-made electrospray ionization stage for a mass spectrometer. I'm not 100% sure about that, but knowing who was throwing it out, I have a pretty good guess.
