Title: Choke value question
Post by: Tapsnap on February 13, 2019, 03:25:39 pm
I found this choke in an old piece of equipment. I have no idea what value it has. It measures 125 ohms when I attach it to my meter. What's the method of calculating the henrys on this thing?

Oh wow, Thanks!
I’ve tried that on other transformers and never had much luck. So it didn’t even occur to me to try. Thanks.
Why is it that the manufacturers of these things almost never stamp the values on the casing? It would save a whole lot of time.

I believe that is a Schumacher choke as indicated by the EIA transformer code of 606.

Almost enough stuff to build a "Death Star".

I'd bookmark the link but they don't have anything in the Thz category yet. However, there's prolly enough to "think" about a Googlebot discombobulatetor.. Really, a 750 watt laser output research bed? Make sure you have the right filter goggles. Thanks for the I don't want to know what your project is page, for the armature physicist.

Edit: Well I did Bookmark the page after after taking a look at the Audio Amplifier page. Downloaded the 25KW power amp specs. Would be interesting to see the schematic.
