I found that I also had an open primary winding on the antenna transformer. I rewound that coil with 24 turns of #31 wire and
also rewound the 2nd RF coil primary with 14 turns of the same gauge wire. Surprisingly, the receiver works really good.
I tried to do the neutralizing alignment using a dummy tube but the audio level of the 700 khz signal I generate with 400 hz modulation
drops so much that my AC Simpson AC volt meter across the voice coil doesn't read it, So I think I will not mess with it.
