So...finished the backelites, extracted the tone control and the electrolytics. They might've been the replacements but are original Philcos.
Extracting of the tone control proved to be somewhat onerous: the tone control is squeezed between the front panel and the closest electrolytic cap and its holder clamp. Without full removal of that holder clamp the tone control could not be tilted out of the hole for the shaft. The holder clamp is held in the middle by a thick steel wire.
This one.
   

Unbending it without any fulcum and wires around was not simple. But I prevailed.
   

Now, about that tone control.

   

The stamped number could not be located in Ray Bintliff's book. Seems to end with 940.
Also it is 3-cap thing. From the "Evolution of 89" I did not see any 3-cap ones used, only 2-cap.
Any help with the info is appreciated.
