Ive been searching for this online.....and its not on the schematic..

on the DSL 100 output trans= Does anyone know what color is what impedance???

Looks like black is ground.....but I cant find any info on the other 3 wires.

Aren't the wires part of the amp on this one, not part of the transformer? Or am I confused? I always mark wire color on the old transformer before removing it, so I can install a new one wired the same. I donl;t need to know which was which.

But maybe these files are useful:

yes wires are on the amp. The new ot wires are different colors (of course) . I found one earlier that shows BLACK is the ground. I looked at the pcb and black is connected to the jack grounds...... so now Im wondering if i have it correct ??? the old ot was a txop 0001
