    It appears I might have the Dynaco PA060 transformer knockoff from Dave Lucas of Lucas Electronics. I had this bought years ago and don't recall the wire cross reference to a stock PA060.
    Would anyone happen to have the cross reference for the wires to stock wires for this transformer and are all the wires used??

    Thank you
    Tony

    Follow the schematic and ohm it out. That will give you a start. With some experience, that should be all you need to do. But, if you want absolute certainty:

    Apply AC power - preferably through a metered Variac - to the primary, and you should get (proportionate) voltages at the secondary so as to determine which windings are which. Given the proportions, you should be able to get a pretty good idea without applying lethal voltages:

    24 VAC on the primary should give you 1VAC on the 5V tap, 1.26V on the two filament taps, 11V on the bias tap, and 71V on the B+ tap (which is center-tapped as well).
