Transformer DCR's

bloozestringer · 19th October 2006, 05:36 PM

Does anyone know the DCR's from any of the following trannies?

Edcor : XSE 15-8-5K, XSE-25-8-7.6K, XPWR106
Hammond: 270DAZ, 270EX, 270FX

A friend is helping do the PS for a Darling and before we started calling manufacturers I thought I'd check here.

Thanks in advance.

My Edcor XSE-25-16-7.6K has 128 ohms primary resistance, presumably the same as the 8 ohm model.

This is what I got from Edcor in case anyone else wants to know.

XSE15-8-5K primary DCR is 125 ohms, XSE25-8-7.6K primary DCR is 150 ohms. We do not measure DCR on power transformers.
