UTC LS 140

says there's a free prize inside, .....so what do you think?   

oh boy!  open the box, open the box, open the box


this stuff is a trip CJ-

I wish I had a better handle on physics, but I'm having a bad math life.

math is the language of all sciences.  i feel illiterate.

open the box before i get depressed(er).

Gee you're a busy lad at the moment CJ.

I would bet every audio trafo within a 50 mile radius of your house is afraid.......very afraid!!!!!

Mac  ;D  ;D

ok same ol thang, only different

this thing turned out to be pretty weird, look at it, all messed up, sittin there like a poodle,


workin those leads like a schoolboy,


ok, so it Is another 31UI, wtf, over? plus, they forgot one of the coils, i am going to call UTC, 


looks like a record player motor, weird, eh?


this is a Hybrid transformer, so spell the lams accordingly,


this is something i have not seen since i worked at Aydin Energy building transformers,  folded shields:


so that center winding in this pri-sec-pri rig is buried under two copper shields whose ends are tucked,

this keeps cross talk down to about -92 db , catalog spec,


more weirdness, bi fi windings, this is the splice from the outer pri to the inner pri,>


shield connection looks serious,


heavy cardboard in between pri-sec, another weird tweak. usually you want  copper in the window,


how do they wind these things? slowly.. we use to put a piece of mono fish line in between, better C,


there is a piece of copper in there, inside the yellow mylar, it gets wrapped around the leads,





first layer.  all thw windings are bi-fi,  200t - 400f- 200t, so twice that = 800 turns , pri, 800 sec.


i  will get the spread sheet up shortly...

Now that is an interesting coil!
