Successful TPU-ECD replication !

Marco is right. The tubes will amplify everything injected, as long as it is within their operating curve and will work within their characteristics.

SS also will not be a good source for charged particles without specific heat-sink setups - tubes are.

There are reasons to use a weak or strong magnet. I don't know for sure how that applies here but the reasons are valid, Im sure. A weak magnet is shown and it has a hole in it. If you want to use a magnet then may I suggest using what is shown until you know why it was chosen.

Sorry for dropping in like this. I spend all my free time on the bench not at the keyboard.

So with a DC polarization characteristic in the ac on the dc drive, a class 'B' this amp could be used. The wave form is above ground.

In my opinion - yes. However I'm not targeting the circuit as an amplifier even though that is surely happening. Remember the info source that uses a 9V battery and a short piece of wire? Do the same with a plate cap on a tube 

I'm thinking more along the lines of making a source for charged particles. Tube with potential between the cathode and collector(plate), two oppositely charged plates with a dielectric between, aluminum heatsink on SS that is switching negative, etc, etc. Once I have a good source of charged particles then it is a small matter to encase and direct them. I doubt that is the only thing that must go on.

edit:

BTW: Does anyone know if SM was Euro or UK ancestry (recent or originally from)?

If so his use of the word 'collector' would then have the same function as the US word for a tube plate. The writings I have seen, attributed to him, indicated he is of UK origin or schooled in English from a Euro country.

In the UK, a tube is called a valve and a tube plate is called a valve anode.
They don't use the term collector for an anode.

True. I'm thinking more along the lines of a CRT or 'beam tetrode' I think the term is. I've been looking since this morning but haven't found it yet. The term 'collector' is used in a tube/valve somewhere.

EDIT>>

I found where I saw it. From an old Army manual on my R390:

"An electrode that collects electrons or ions which have completed their functions within the tube."
