Which option is correct?
sorry... what means ">" ?
btw i just bodged the fix on the pcb... nothing major 😀
keep in mind that thoose pcb are never meant to reach the "public" in the form you are seeing now...
so can be mismatch in naming and not "optimized" stuff.

OK thanks.
There's a esch several inconsistencies between the circuit and the PCB.
I just check and the only error is the compensation cap in wrong place, sorry
actually the names of the components are not the same between simulation and eagle

I have no experience at KadSoft Eagle, I use the simpler SprintLayout program. Translated your circuit board into this program. The numbering on the diagram corresponds to the printed circuit board.

Eagle isn't made by CadSoft anymore, was acquired by AutoDesk.
Anyway... not sure why you felt the need to redo the whole pcb... but i guess is a good thing.

Germanium circlotron, is that even legal? 😉
Makes me wonder if anyone's made a GaNFET circlotron yet? That might present a few challenges but be a little bit more upto date!

The amplifier is assembled on powerful germanium transistors. It must be heard. Unique low frequencies.

on the simulation i have 30p, but it was a test, i think you should use 39p for start and lowering after
i have 47p in real and it is too high
what do you use as bipolar ?

May try 2SA1538(E,F)? (120V, 0,2 A, 2,2 pF, 400 MHz).
yes if you have good pairs
Did you measure j113 to fit pairs?
