It's probably simpler if you use FETs.
and plastic
covers to make a 'solid state tube'. The heat sinks would
look like Seleium recitfiers fins... :)
I've seen that as replacement for rectifiers and RF Power tubes...
I seem to rememebr seeing references to little PCBs you could fit over
the pis nf defective 01As (between the valve and the holder) that
contained an FET and a few other bits and let you keep 1920's radios in
operation.
