94315 / A23934-2 / S944 Stancor Transformer Data Sheet

Hi,

Do someone have the 94315 / A23934-2 / S944 Stancor Transformer Data Sheet?

I will appreciate any help!

Thanks
Opacheco

Hey Opacheco. I guess you know that’s a custom part. None of my catalogs have it. But since it’s an audio transformer (identified by the “A” prefix in Stancor world), you should be able to measure it up. Even a guesstimate of max level is possible using CJ’s inductance charting method.

I think the only thing you can’t estimate from measurements easily is whether it takes DC, and if so, how much.

Hopefully you’ll get lucky and someone will have info on it.

rackmonkey, thanks a lot for your response and info. I don't know CJ's measurement method, do you have a link for the CJ’s inductance charting method?.

Thanks
Opacheco.

Here you go:

Measure DCR on the windings, then multiply the DCR values x10 to get a VERY rough, ballpark estimate on nominal impedance of the primary and secondary (this is the least accurate test you'll do, and it's much more art than science).

Calculate or measure turns ratio. 1V AC in, measure the voltage out for the ratio.

Perform the inductance tests above to get primary inductance and saturation level at the lowest frequency of interest.

Good luck bruh!

I have the same problem (A23934-2 94315, three of them in good condition) and don't know what I can do with them! They were part of a modest collection of pro audio parts from Craigslist.

Pretty heavy. About 1x1x1.34". 9 pins with 7 used (wired up to something) & the other two jumpered together.
