Yet another Zenith To identify

[zeno]

Thinking back over CC2's there were several plug ins. They
are marked by white paper or plastic tabs on the chassis contacts.

Speakers ( 2 brown)

A cap that just killed the bass on small speaker models.
( 17 & 19" & maybe low end 23 & 25" )

Volume control (not all). The VC changed a DC level to the IC
NOT the usual coupling cap-VC-coupling cap.

Mute between channels. (? blue-white ?) also raster mute
went to the 9-88-# on these IIRC.

Sliders can get very bad. Try cleaning with WD40.
Unhook everything but SPKR & VC to narrow down.

I've unhook the "tone"pot from the sound module and the low rumbling and tin can sound is still there, so its not the "tone" pot. Unhooking the VC...well I get no sound (of course).

I tried with another speaker...bad sound still there.

I will get some wd40, but I juiced that sliding pot pretty good with my go to cleaner and it didn't do a thing. Will try the WD40 anyway,

That cap that killed low frequency sure does sound good because its how I would describe the sound : high frequency are there but anything that is in the low spectrum is kind of garbles and muted... I imagine that cap is on the sound module? And if it is, could it be a high enough failure part that both my sound module could be bad?
