I bought a couple of the "David Winter" FM modules FM Converter for vintage radios (paleophonies.com) to experiment with. I'm going to install the first one in a Philco 118.

I have been using this 118 chassis with no cabinet in my shop for many years, it just sits on a shelf with an H-13 speaker.

The first step has been completed, replacing the electrolytics with film capacitors. I had restored the chassis several years ago, it still works well. The past few years, I have been using film caps to replace electrolytics so, I decided to do that upgrade.
This is a four section 1uf 1uf 1uf 2uf. Since this cap is clamped from the top, I cut that end (done previously). A piece of 1" PVC pipe fits the inside of the can snuggly and is used to hold the cap on the can. I am using "orange dip" film caps.

The main filter caps were done a little differently. I cut the bottom ends off and made nylon plugs to replace them.

Heat shrink tubing was used to insulate the connections from the can.

I want to use the band switch for switching the FM so, this will require a new switch with more poles and 3 positions. Coming next.
