Has only bought one of these?

I dont want to make this particular kit. I have an idea of a design and want to try out different valves. I’m thinking that I could build this but with a few modifications, so I can easily change out the plate and cathode resistors in order to try different tubes. For the different pinouts of the tubes I would have to make adapters, but this shouldn’t be too much of an issue.
