Well,
Thanks to Kirk I am a happy albeit running out of space (well.....having run by now) owner of Philco 112X. The "X" has been on my list for some time, though I thought it would be 14X or something of the similar ones. The radio looked great and the price was just right also.....so I caved in.
Since the pics from For sale online will eventually disappear together with the thread, I have decided to repeat them here.
These are front photos taken with my tablet. These are likely to be rotated so I would ask moderators if possible rotate the pics so one would not have to twist one's neck in order to view them.
Now, the back is off.
Rfeenstra, yes there is some burgundy soft cloth lining the back. It is in decent shape and won't require replacement.
Upon opening I found an envelope with some extra grillcloth.
I wonder if Ron could tell me if it is close to original.
These are how it looks and zoomig in on the pattern.

The one thing I am always afraid with these radios is the speaker being bad. Considering the grill cloth was replaced, I did not have any way of knowing what shape the cone would be in.
Before I even started taking the radio apart I took the meter to the speaker's plug. The results were encouraging: both the field coil and the output transformer's primary were good.
Then I took the speaker away....Jubilations!!! (S&G) the cone was in great shape with a small hole which I schmeared some rubber cement on. Almost looks new. Just dusty.

Now with the chassis out,
First thing, as the previous owner told me (good thing he did) he tried to fit the dial with some lighting, LEDs with batteries, so it would glow.
As could be seen, the screw waas about to touch the dial, so if rotated it coul scratch it. Luckily no one did and nor did I, so the dial is good.
And the original lamp is there too.
Here is the front of the chassis.

Tin can caps restuff.
First of, they all had right capacitances, 2x0.25uF in one can, and 0.5uF in the two others.
I restuffed them just the same.
The steps:
The cap
The innards
Soldering the GND lead in
The cap is inside
Reusing the fishpaper

Good stuff (restuff)!
Did you ever figure out the grill cloth?

I am not at that point yet.
In fact the grillcloth looks like some Philco reproduction type, so I will have to investigate first, as to if it is and if it an appropriate type.
Opinions and advice are welcome.

Today I rebuilt aluminum can caps.
I used 8uF film instead of electrolytics. They fit just fine, close enough in value (8 vs 6 uF) and were easy to mount.
Also the aluminum can caps themselves ( not original but good-looking) lent themselves to very easy gutting. So I rebuilt the two in 30 minutes. Right now they are waiting for the epoxy to cure.

Today I
1. Installed the electrolytics back in their places.
2. Desoldered wires from several lugs of the filter can and...all of them were within 20%. I decided at this point to not rebuild the can, especially considering most of them except one are working at low voltage.
3. The volume control had no contact from the wiper to the resistive element. The resistor was at some point subbed and the replacement is the type with a snap back lid, so one good blast of Deoxit Fader Lube and voila....it works.
4. All audio transformers seem to be ok.
5. Filter choke ok.
6. All RF coils seem OK.
7. Tone control. Even though the capacitors inside seemed close in value to the specs, I decided to rebuild. Plus the wire going to it is all brittle and breaks readily.
That is it for today.

I like your work, sharing your knowledge. Although my dad passed away years ago, I still think of him and the little things like when taught me how to hunt; indeed, I have his old Winchester 1200 shotgun with which I blasted my first (and actually my last) squirrel out of a giant beech tree! Keep up the good work.
-Simon
