And interesting mods. Pin 4 grid1 should be negative to get amplification going. Tube handbook say...

Re: HOT LF-out tube
Hi Jan
Measure the current of the Plate. It must not exceed 13 mA.
Check Grid#1 voltage. Should be minus 1 V.

Re: What is C3?
Hi Matt,
That's just what it is, a very small capacitor formed by a few twists around a wire.
Here you can just see it:

Re: Antenne for Paraset
Due to the 2 var caps Antenna and tank tuning, the Paraset is very forgiving concerning antenna length.
But it was designed to end-fed antenna, and not hang up, half wave high!

Re: Capacitor values
Only read it today. So you want to put a 200 pF cap in series with a 200 pF variable cap. That will work, only the characteristic of the tuning will be a bit "odd". Throw in the values here: https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-series-and-parall...
