I have a Philco 16 code 121 cathedral set. I am trying to undo some previous repair attempts. There is an inter-station noise suppression adjustment on the back of the chassis which seems to do nothing when I turn it. There are also two black wires coming out of the top of the chassis (far left side from rear view just in front of the two electrolytic capacitors) which I THINK should go to a toggle switch (missing). Those two wires are connected to no switch at present. Should I tie the ends of those wires together to simulate a closed switch?

Also, is a good schematic available for the model 16 code 121 and is there a parts list available that actually shows the values of capacitors and resistors? The one in my Rider's does not.
Thanks,
Mark
