I love the top cap connections on those tubes , they remind me of the band "Devo" , specifically the "whip it" video ....

Looks like you did a nice job on that set.

I'm sure if his Minerva is goin' wrong he'll whip it good.

That FM converter reminds me of Pilot radio's Pilotuner FM tuner....It was basically a tube FM radio sans audio amp with a phono input switch built in. The whole shebang came in a nice simple cabinet, and was a good preformer for the era. It was fairly sensitive, and could sound REALLY good if tuned up well. I used to have one that ran great, but had it's cabinet ruined in an accident. I sold that one long ago, and finally found a nice example to replace it.

These top connection shieldings are nothing special. Even though the peoples receiver had one on the top of the AF7.
Pilotuners are also quite cute devices. I like the way they look!

Here you can see how my module looks if it is not built into a Radio:

Here an external FM receiver from another manufacturer which can be placed under an existig AM Radio:

Even though I tried my best to implement the FM receiver as good and as professional as possible an unwanted effect occurred: Due to the fact that the FM receiver is permanently on as soon as the radio is switched on it was possible to receive the FM IF on shortwave
I want to Point out that this was not mentioned in the instruction manual of the FM receiver so I didn't think about it earlier.
After a little bit of I decided to build in another switch which turns off the FM receiver if the radio is operated on AM. This I realized with a dial string which wraps around the band selector axle and opens the contact on AM and closes it on FM mode.
Also this modification should look as authentic as possible like the rest of the radio. I only used old components from junk devices from the early 50ies I parted out some time ago except the dial string wich is new.

I hope I can call this project finished now
