Default Help identifing RCA transformer

Could anyone help me find out what this power transformer is and the connections? It is an RCA power transformer. The numbers are:

27465005 4

Thank you for any help you can give.

If you don't have a meter, GET ONE. Measure the windings with an ohmmeter. Highest resistance will be highest voltage. Primary is usually in the 10-20 Ohm range, but a large transformer will be less. Once you've identified the primary, connect 120V through a 100 Watt bulb (connect a cord with wire nuts) If the light bulb glows brightly, you have a shorted winding or you guerssed wrong on the primary. CAREFULLY measure secondary voltages - disconnect power, clip your meter on a pair, then plug it in.
