OK, so now that I am more or less done with the 18, I eventually got back to this one.

This is the sch.

Took some pics of the underbelly.
The set was repaired at some point and that point was probably when I was..well, not in diapers - we did not have diapers, but as we say when I was able to walk under the dinner table without stooping, which I think translates as knee-high to a grasshopper.

   

It was done fairly neatly - the "new" cap is secured with a tin band soldered to the chassis (I thought the chassis was aluminum but soldering indicates otherwise, probably steel).
You can see a cut wire from the original cap, which was not removed.
   
It's the grey cap at the top-center of the chassis.
It is 16uF and not 12uF like it should be, but I guess that much deviation is OK.

Oh! Is it me, or did Philco connect the capacitors across the power cord without discharge path? Granted, it is 5nF equivalent but it will give you a painful pinch if touched after it was extracted from the outlet during the peak voltage.
Since it is a RPITB to re-rout it I intend to introduce a 1M resistor just across. The caps need changing anyway, the only backelite block in the whole set. The rest seem to be the tubulars. They all marked as PHILCO so I intend to keep the shells to hide the yellow.

OK! Good luck to me!
