UX201 or UV199 Substitute
#16

Of the 6469 spare tubes I have not one is a 3Q4.

I have made the adaptors for the UX99 and UX120, but I have not tried them yet. I'll probably get to that soon. One of them is set up for the 3S4 - but with 90V going to the screen. This is probably going to work but with some extra screen current which would not be detectable - unless the tube fails.
