Valve heaven mainboard
This is the PCB you can use to build the valve tester here
https://valveheaven.com/2015/03/an-inexpensive-easy-to-build-diy-valvetube-tester/
Despite being easy to build this is extremely versatile, especially if you have a bench dc supply to cover different filament voltages
I can claim no credit as this was produced by someone else. I found a copy of this PCB on PCBWAY which required some tweaking, which I did.
I know this board works as I used it for my own build, which you can see in the picture.
