You already have Tx, D & C.
No reason why you cannot use the same MOSFET.
Else the old IRFP240 will also do.
CRD can be just a LND150, plus a 2W resistor to suit Idss and desired voltage.
And then use your other remaining C to parallel the R above.
I am sure you have them all lying around.

i like it , even a french guy can build it 😀
i already have 1,5W E55L tube Spud amp , with nearly the same config 140V 55ma 3,5K transformer. it will be fun to make a direct contest Tube Vs Sand 🙂
Just as in a tube amplifier. You and I have horns so the slight loss of power will probably not be noticed. So simple I may have to give it a go.
My experience is all things equal with class A there is not a appreciable difference. It comes down to your preference for SS vs tubes.
also difference between triode ( I suppose you have) and pentode
power is overrated
Don't believe so. My understanding is they use output transformers just as they do with their tube amplifiers.
I knew if I was wrong someone would correct me. Always thought they used output transformers. Zen Mod is the man. 🙂
if that's for believing , all you need is to take a look at their xformers , top.
power xformer having proper schematic sticker , autoformer also ..... even wearing a title Audio Autoformer
example attached (clogging da thread ...... but this is Papafun one , so who cares) .... and yes , overcomplicated drek .
just rename xtension from .asc to .pdf ..... I cheated , to upload it here
