I presume you have these manuals ...Knight KG-600b
I had to improvise with an old Funke tube tester before, and it was to find some other tube that was similar, and try and interpret the settings. With the Funke the parameters were voltages and currents, so it was easier to create a new card for the tester. With yours you have a few complexities: Center tapped directly heated tetrode.
What is your goal? Just check emissions, or get enough points for curves for matching?
