I have a NOS of these coming:
Sophia Electric 274B
I really need to go back and try my vintage Type 80 (Mercury filled) recti. It has 4 pins, so needs a cheap adapter.
I also have a type 83...both are 5v rectis and can be used. Cost me the princely sum of $20 in total. LoL
These Mercury vapour rectis are the favourite of Greg in the UK and a world class audio designer pal of mine.
