Ok, off topic etc. but I know there are Gear Heads on this forum (and others I'm sure) who'll appreciate this.

Wow!
Makes you want to build the worlds smallest AM xmitter, pair modulated by a pair, say a miniature 20V.

Also enjoyed the Farrari vid on same YouTube page.

I got a box of pencils..

but more physically right looking might be 6AK5's.  short and cylindrical? just fake the plate caps.

Nice form factor for the larger tubes. I guess the earlier stages in the chain could be pencils for the drivers with half the tube under chassis, etc.  so what would be scale based on the 6ak5's ?

And you have to machine all the loading amd tuning caps, coil forms. Transformers, mod and power , chokes, etc. might be doable with the small form factor size.
