Philco 116B chassis restoration
#1

This 116B was a Craigslist find that Matt (wardmc1) saw and alerted the phorum to the post.  It was only about 20 minutes from me.  The cabinet is painted white and will get stripped this winter if I can do it with citristrip.  If I need to use something stronger it will have to wait for outdoor weather.

The chassis is dirty but not too rusty.  Here is the LINK TO THE SCHEMATIC   My main concern was the extra rotary switch on the back.  Lord knows what someone has done…

The chassis came out of the cabinet without issue.  Surprisingly the two front rubber cushions are very soft and pliable.   I did buy new ones assuming they would be bad but these still seem good.  The rubber on the back chassis bolts are another story, definitely needs replacement.

Once I got the chassis out and could see what the switch was connected to it became obvious that its simply an aux input switch unless I’m not understanding things.  It switches the grid cap for the 1st audio 77 tube between the screw connector on the switch face in one position and the normal connection to the front end of the radio at cap#65 in the other position.   It was a little difficult to figure out since its actually a 3 position switch (probably something the person had in the junk drawer) but is only used in two of the 3 positions.  Most of the connections and wires are actually grounded wire shielding.  The switch location in the circuit is the red box.

Here’s my set of notes as I deciphered the wiring

I think I’ll take this extra switch off.
