Hi Pese,
Steven said he origionally got the idea of electron circuits which used the rectifier tubes, not that they produce FE....
to go further you need Triodes.
The tubes first made by Lee De Forrest when he placed a spiral shaped grid between the cathode and the anode so he could influence the electron beam flowing in between.
It's intresting you mention the Gamma emission,it involves the compton scattering and all is intresting related to electron emission.
Specially because we know the voltage has to be high enough to "make the violing work" so to say.
But if that is the true behind the TPU?
i do not know, could be i hope we will find out.

MS was trying wit Rect DIODES-Tubes.
5U4 5V4 that work 350V and about 220mA (about 80 Watt)
the dubble triode that now act is (i must look , but i think 2 time 2 watt maxium.
Tesla worked with pentode tube ( in US = Beam tube) (abot 5 Wat , and an
weekly diode system in same Tube that can wower lower than 1 watt and les than 50mA (about)
Must see the datasheet 70L7.
6 pcs was in his car (but the pentode possible woreke faor frequency devider to form an
low frequency for his AC- Motor.
BUT it is to wonder that tube wit 70volt filiament heater was used !
Only 12Volt Battery on board !!
6 and 12 volt tubes was also 1930-1940 in any construction on the marked.
To use 12nq7 or the lower cost 12at7 12ax7 enz or some high power triodes ,
are equivalent to SM construction , that also cant produced the "invented" effect,
(Only some week nois from barium filament can be (possible) be an effect.
Pese
Attention to understand.
70L7 !This is NOT an rectifier beam tube .
this is an diode rectifier system in in (very week type)
and an stronger Penthode (US say BEAM) Amplifier tube in it.
cathode + 3 gird + anode.
3.gird will alltime connected with cathode.
RCA PATENT say BEAM Tube for it (RCA Patent) .
The (older) Penthode System from TELFUNKEN was
exacly same .
The US Patent say , 3.gird connecte in tube with cathode.
The German Tube externly. So the US have an grat
Patent for his RCA 6L6 Tube (in Audio Amplifier)
an the German one EL34 (EL36) is the equivalent
(better) one.
This only to say , what a BEAM-Tube is
In any way possibly the typ Number 70L7 , can possibly be WRONG
(was not Informated from TESLA !)
So it ist very hard to examine to undersTAND 2HIS WORK2
