I have an AA5 Motorola of this receiver family. I may just go back in and change the ceramics to film like you did.
I added a 22uf bypass cap across the 50C5 cathode resistor, like with many other radios. It got louder but "screeches" at higher volume.

Was this cap normally omitted to introduce negative feedback (degenerative) to reduce distortion? Many Zeniths use an RC feedback network from the OPT.
