While troubleshooting the no bass amplification issue, I think I found the culprit. The choke #104 is reading 164K ohms. My first thought is replace it with a 2K 5W resistor and increase the 1uf electrolytic, just like you would for a speaker, but that parallel 40K resistor threw me. How do I factor that in?

This is the parts catalog.

32-7528 choke is 65H, 10mA, 2,250 Ohm inductance.
Find a suitable one.

Ah, now where to find one.
I've into this before on smaller sets, I now recall. Hammond makes one that is only rated 8MA, and this 37-690 has two stages of bass amplification, so 8ma may be pushing it.
