I made a selector with a switch lorlin PT6594 and a simple 12V to 170V HT converter + one resistor.
I made it in 3 different modules, but you can build it on a single board, with a socket to test your tubes. the pt6594 have 11 positions you can test from 0 to 9 + a decimal point. I made also an arduino + K155 chip, but a misconnexion of the 170V will destroy either the arduino bord or the chip. with a manual switching, you can also insist on poisonned digits to clean them.
