Howdy, Paul. Wondering if you might have any off-line advice before I order. What I'm starting with are one complete set of tubes, nothing fancy. I have an electronics and electrical background but it's mostly computer and industrial. I'm an industrial electrical/electronics and robotics technician so I do know an ohm from a volt but I am buy no means a consumer electronics expert, nor would I ever claim to be.
How many do you need?
