Thanks Don,
The Am is not included (but somehow affected) and the function of the 6BJ7 is listed as a discriminator
and transformer is mounted on a PC board.
Yes, the 119 preceeds datecode as 119-61-36

My last resort will be to pull the same transformer out of my yet untested Philco RT-400 tuner, disconnect coil and measure the bases built-in capacitance.
