Maybe C3 leaking / shorted? It appears to be a "gimmick" (2 insulated wires twisted together., but not shorted.) Make sure that only the insulated wires are twisted but that the conductors don't touch. I am not sure why it is there, but it is in the 37-84, a set similar to yours except that it uses Octal tubes. It is not in the 80 and 81 which use a 36 Tetrode as an Autodyne Osc / Mixer, nor in the 89 version that uses a 77 Osc Mixer like the 84. If the 2 conductors of this twisted pair touch, it essentially shorts the antenna to the cathode of the tube.
