UTC LS8 - any info?

[rafafredd]

I´m searching for some info on this transformer. I can´t find it on any of the five UTC catalogues I have... :?

I can not find anything except a hit linking some cached E-bay stuff.

Do you have one?
If so, what color is it?

BTW, here is a link you might like:

Yes, I have one. It´s a grey one with the model number engraved in a metal plate. Looks like the old A-series grey ones. Maybe it´s a very old 40s UTC LS type number.

I did some measurements of inductance and DC resistance and it looks like 600+600:200. Althought, on the 600Z windings, resistance seems a little high, at 150R, so maybe I should use it with the 600Z windings in series, for an impedance of 2k4, and a dc resistance of 300R... Looks better this way.

What I would like to know is if is gapped or not. I think it is gapped, but not sure...

Don't know why they would gap a 600:600, but maybe.
Could be a 10,000:10,000 bridging type.
Did you scope it out to check turns ratio?
Any inductance measurements?
