Magnavox Astro Sonic chassis number help please

Can anyone tell me what this chassis number means?
Been searching for a bit now and coming up empty handed.
Guess I expected to see r204 or r214 on the little tag

Hmm that picture didn't show up properly.
Here is a direct link to it on my photobucket.

Never mind. I completely missed this other tag.
Turns out I have the manual for the R204 rather than the R214. Oops

IMHO--The "C" indicates the # of the cap sitting near it--the "R" mark indicates the resistor number.

Thanks for responding Ron
That not quite what I meant however.
I was just referring to the model of the chassis, not the components on it.

Have a good evening.

From what I can see in that pic it appears to be the tone amp board:

These are the schematics:

The bulk of the amplification takes place in the second and third schematics.
