Schematic please. On-line Riders does not have it.
What is a triad audio transformer?
Do you mean the Triad brand, which exists and is old by Mouser, or something else?
To measure resistance (promary, the xfmr usually needs not to be removed from the circuit, but the resistance is not very important; inductance is and for this you do have to remove it.)
You need to measure inductance to see if there is a turn short, which is probably what it is.
I suggest that the transformer by now is bad.
Also, sometimes it does not go bad on its own, and a tube (or tubes if it is a pushpull) make it bad.
You need to check the output tubes also.
