Ok. Here's the real values:

Red to Red = 92.7
Black to Red 1 = 45.9
Black to Red 2 = 46.6

Orange to Orange = 52.6
Black to Orange 1 = 26.16
Black to Orange 2 = 26.73

Thanks you guy's. It's seems to be a nice, big, heavy transformer. Now I need to find a good project to use it on.

DC resistance is more likely to be unbalanced than voltage, so is less reliable as a guide.

in that case we know that the secondaries were not wound bifillar, and at least we can get an idea as to how much current draw is possible without the terminal voltages dropping by say 10%....

Ok. Here are the DC resistance values:

Black to Red 1 = .4
Black to Red 2 = .4

Black to Orange 1 = .3
Black to Orange 2 = .3

I hope that's what you meant by DC resistance readings.

You're on the right track here, 1980s-early 90s with a cd player on the bottom and record player ontop if I remember correctly.

Chip amp.

These transformers I usually throw away because their windings are really just 'odd', but good luck finding a nice chip amp and cd transport project to put it to good use on.

Yeah. I found it at the landfill in the electronics bin. I was just looking for parts. It had a nice, big heatsink in it and Toshiba 2SC3281's and 2SA1302's.
