Title: Swinging Choke specs Post by: stevef on July 18, 2010, 09:35:36 AM I have what I am guessing is a swinging choke.
It has the following on the label: REACTOR Mfd. by Super Electric Prod. Corp. for Radio Receptor Co., Inc. Part No. 932 Type No. 2-RR-2 6/60 H 4/05 Amp 10000 Ins. I think there is supposed to be a decimal or two that did not show up when they stamped the tag. Is it 6 to 60 henries? Is it 400mA/50mA? If inductance decreases as current increases then I effectively have 6 Henries at 400 mA? Title: Re: Swinging Choke specs Post by: KM1H on July 18, 2010, 10:01:20 AM Yup

I have a smoothing (non-swinging) choke rated at 6hy 500ma at 7500 v and it's around 28 lbs. So yours at 39 lbs with a bit higher voltage and a swinger sound resonable. If it were 6 hy at 4 amps it would be much bigger, I think. Title: Re: Swinging Choke specs Post by: KA2DZT on July 19, 2010, 02:43:40 AM not so sure... how big is the thing??

The choke is 6hy @ 400ma - 60hy @ 50ma. Never saw a swinging choke that had that big a range 6-60hy. It would be interesting to measure the choke with no current, probably won't measure anywhere near 60 hys. 39 Lbs is a little heavy for a choke of that size, but, with the 10kv high voltage insulation and the cast iron end bells, it might account for the extra weight. Manufacturers of chokes used different methods for measuring the inductance of chokes. I have measured many different chokes and found that the numbers are all over the map from what they are labeled.

Both of us couldnt lift it. ;D Carl |
