Ok...Ok...Now you've done it...I gotta speak.

First...It's very common practice nowdays for "balanced" inputs on sound
equipment to be floating.  It's very uncommon for center-taps on input
transformers to be grounded, let alone exist. I think that I can say this
with 99% certainty for the equipment being sold today that still uses input
transformers.

Second...Don't you dare use an ohmeter on your input transformers. The DC
used for the ohms current source will almost certainly magnetize your
transformer's core, ruining it for anything musical. Once this happens, you
might as well add it to your collection of audio transformers being saved
for your boat anchor.
