Stancor P-6165

[WA4WAX]

This thing is 400-0-400, with 5 VAC and 6.3 VAC

Does anyone have a guide to the wires?  I think I have the HV and CT identified.

Thanks!

Two black wires 117 volt primary
Two red wires 800 volts center tapped.  tap is red with yellow tracer
two green 6.3 volts    center tap is green with yellow tracer
two brown 5.0 volts,    sometimes 5.0 volts is yellow.....

Often the wire colors will be faded on a transformer this old, but an ohmmeter is your friend.  Isolate the windings with the ohmmeter, then apply 12 volts AC to the primary and measure AC on windings at 1/10 rated voltage safely.

Any old ARRL Radio Amateur's Handbook has the color code for transformers and other components in it.
