Both my first two console radios, Philco 20 and Zenith 9S262 had output transformers' primaries open. Both got replaced with modern ones, a bit oversized for reliability.
I suspect I know the reason for the Philco - one tube in the output pushpull was gone, so badly it took 1.4k section of the multitap resistor with it. Although that might have been a consequence of the fried transformer. Which is not even important as long as it got fixed.
