Mystery Power Supply

[nineno]

Hey guys, I have a mystery on my hands.

At some point I acquired a transformer from a tube amplifier. It looks like a nice, usable hunk of iron. I though it might have secondaries that would be useful for my current "junk box" SE mono amp. So, this morning I screwed the secondaries down to a terminal strip and hooked a Edison plug up to the Primary.

As close as i can tell the transformer has these outputs:
6.3V Center Tapped (registered 7.0V unloaded)
(using green, grn/yel, green connections)

240V (unloaded) Non-Center Tapped
(using blue, yel/blu connections)

100V (unloaded) Center Tapped
(using red, red/yel, red/wht connections)

I thought the mix of center tapped and non-center tapped was a bit odd, as well as the color coding. I guess I'm just used to solid colors on the HT sides of a center tap with a stripped lead for the CT (like was done on the heater taps). The 100VCT line on this tranny was odd with dual stripped outputs, it seems.

There is a number on this transformer as well. The number is: 83-692-000-606-8-49. If anyone has a transformer cross referencing book or some other resouce that might shed some light on this situation, please let me know.

Thanks again,
