Hello morzh,
man that set is got dusty chassis and it is funny that dial looks like the same style that is on my Zenith model 755 .

that chasis is the size of one their early Tv's and I bet it weights like one too.

One thing I like about bakelite blocks you can easly hide your new capacitors and they are fairly easy to do .
The cabinet looks in fairly good shape thou.

Sincerely Richard

First and foremost, this chassis is a back-breaker.
Then, it has that big capacitor block, which I hate, and which is the 3rd one I am dealing with (111 and 86 were the first two, and I still have not defeated the latter).

I never have seen a schematic with so many discrepancies between it and other schematics (like I said, I see 3 versions now, the one in our repository, and two (earlier and later) in Riders, and this is without the fact the Nostalgia version has no values in it).
I still have no parts list from any of the document. Maybe someone knows where it is.
And I wonder why Rider's made a piecemeal out of it, having 1-sheet sch in 1st book, the chassis photo in another, and the alignment procedure in yet another one.

I had no such problem with 111, 112 or the 86.


The Philco was modified during the Philco times, or at least by some Philco repairman.
All parts used in repairs/mods are Philco, and are time-appropriate. That 5K resistor on the capacitor block that should be 13K: yesterday I de-soldered it, and the soldering was as factory as it gets.
Also, there is an original tubular Philco 0.015uF cap (200V; I would use at least 400V at the time) that is not on the sch, not in the chassis' photo, but is soldered from one of the AC line wires to the chassis (a Y-cap).


I checked the volume pot; it is bad. End-to-end is a few Megaohms. I believe I changed it in 111; I will have to do the same here.
The tone control...well, I have tons of experience rebuilding these (it is yet to be dealt with).
