Hi guys.
Decided to start on the 118.
This one I picked up on my way to get the 37-116 in MA I bough for Peter almost 2 years ago, in August 2014.
If anyone remembers, this was from the guy who all of a sudden decided not to sell it - he got offended by something. But eventually I got it.
The cabinet is in decent shape: arch support in one place separates a bit but that's a gluing job. No bowing, pretty solid.
No screws hold the chassis in place from the bottom - it is held by the two brackets in the back. Don't know if that was the intent: the brackets are clearly factory but the missing screws I am not sure about.
Anyways, here are some photos:
As you can see from the last photo, someone repaired it before: almost every backelite block has tubular caps soldered in parallel. The cord is not original  which is painfully obvious.
Very familiar picture: it is very much like the 18, which I restored 3 years ago or so.
Good news: the speaker has both the field coil and transformer good.
Well, this is it for now.

Looks like a clean rust free chassis and good cabinet, always a big plus. Never seen the rear chassis brackets before. interesting.

Yep.
Now I hope the RF coils and the interstage and power xfmrs are good.
The rest is easy.

yes those are factory. Does yours have the bottom screws?

I've always liked the 118 cathedrals and that one looks like it is a very nice example. It should clean up well.

Kirk! No pressure! But you will have to meet and beat the expectations here! Which are running high!

Howdy!
If anyone knows:
This here picture shows a free hanging ground wire that is attached to the ground lug of what looks like the cap #34, from the same point where the flex resistor #33 attaches to GND.
This is the way it was when I pulled it so I do not want to spend a whole lot of time investigating what's left with no GND. Plus to that the chassis was at some point repaired so it just might had happened that the wire was unsoldered (the forming looks like it was wrapped around a backelite cap's lug) and left this way.)
The soldering and the wire look original.
Anyone has a chassis to look at and see if it was there originally and where it goes to?

Anyways,
As I just wrote in a separate post, there is an error in the sch in Rider's - a missing tie dot. Kinda obvious, and typical - same type errors we have seen in many Philco Rider's sch, like 90 and such.
OK. I have rebuilt a quad lytic cap, 2x1uF and 2x2uF.
Here it is.

And finally.
This tail will go inside the clamp providing the connection of the case to chassis. It won't be seen.
This is the clamp.

Nice job Mike. Did you figure out the unconnected ground wire you asked about ?

No. Methinks it is just a ground that was going somewhere befor it was unconnected during one of the repairs and forgotten about. After all it was not near anything it could short to so it lived happily many years after that, just hanging there.
Unless I find some use for it I will remove it.
I was tempted to look into my 18 chassis which is almost the same but I hate to start pulling it vrom the radio. Not that important.

Continuing recapping.
I realized the 73 cap is dual. The way it was installed it wasn't. They installed a single 8uF electrolytic. And then I followed. The cap is supposed to be a dual 8uF/10uF cap, the latter decoupling the chassis to the rect neg. The famous"plus to chassis". Well, it is a low vokt guy, with value m ot critical so I installed an inconspicuous 33uF 100V cap in a convenient pkace, right between the pin of the low ohm bias divider and a backelite block cap's chassus bolt.
Another thing, the 42 driver shows a cap to chassis FROM G2 with nothing more. I think it is a mistake. In the chassis G2 is connected to the plate.
PS. Just checked the 18 sch. Yep the plate and G2 are conected.
