I was at a college football game last night, freezing my azz off, watching the home team lose, and to add insult to injury, this thing fell off a utility pole and clarked me right in the noggin!

What shall be thy punishment, ol sacred Lab vultures?

CJ,

Well if it me I would have chopped it up by now... for no other reason than to take out my anger on the inanimate objects that caused my precious body grievous harm :green:

Thy death shall be by... blow torch... Hah hah

CJ, see what happens when you torture poor transformers? Do you?

They are after you! You know what it's like with transformers... It's a family thing.

Don't be surprised if you are confronted by the ghost of Marinaire or Gardners at the end of your bed in the middle of the night.
 
OK, this thing is pretty cool.
4 identical coils, about 17 ohms each, 12.7 henries each, 1:1 ratio to each,

flatter than a pancake freq resp, and draws very little current in the lower registers, distorts the low freq waveformes in an almost round way, instaed of jagged weirdness like most transforners, it just looks like two semi-circles placed at the top and bottom of the cycle.

will work on other stuff am. this is going to be a tough guy to saturate and get a BH curve, but we will hook it up to the variac and make it squeal like a stuck pig! :razz:

Yeah, boy! Hack that bitch up!

That's the most dangerous-looking photograph I've ever seen! :green:

Peace,
Al.

I used to see a lot of these when I worked in radio. It was the transformer of choice for STLs (studio-transmitter links).
 
DAM CJ sounds like something that would happen to me going along with studio floods and mending limbs. I hope no concussions or anything serious. Fook it up and then hide the body in the hole. :thumb:
 
I think these were broadcast as well. ADC is still around, but they don't do anything like this anymore.

I think they misspelled development.

Exactly, there should have been an 'i' between the 'v' & 'l' :twisted: :wink:
 
Wow! Thanks for the cool links Dave!

I already know the winding struture from someone who has done a take apart, but I want to see this thing in person anyway. Will take it down to the coil core assy.

Will hack it tonight after work.

The torch is on, its dark, and I'm wearing sunglasses.
Not to mention the ear goggles. A foreigner called them that back in 84 and the name has stuck with me since. Ear goggles. Perfect!

Anyway, got froze out last night, (40 degrees is a freeze out in California) but it's lights, camera action!

I always say every xfmr is different, and this one is certainly no exception.

First, the boring details, then the stuff you really want, The Carnage!

Boring detail #1, freq plot:

OK, now the fun stuff!

This did not look like a transformer that I could finesse my way into, No sir, this sucker is built like a tank. Rip it up, tear it up, hammer, chisel, torch action affair. Saves time, and it's more fun!

So, spool up Uncle Bridgeport:
