I'm new at this, but I'm old school at heart. Where would one start to build a 50 WPC two channel tube amp? I'd like to keep the cost under $400. BTW, I know very little about this, but I'm one of those people who learn by doing. So at the very least, I'll know what I did wrong.

50 watts per channel would require a very large very high voltage single tube or two or more tubes per channel in a push pull or parallel push pull configuration. Keeping it under $400 would be next to impossible with the cost of the power and output transformers alone reaching that.

True your speaker efficiency determines how much power you need.

A full tube amplifier kit would be the best place to start. The design is already tested and you get all the parts you need to built the kit, along with instructions.

A very easy and basic kit is something like this PCB based kit.

Here is kit that is a litte more involved with hand wiring.

Here is another with more power.

Google tube amp kit and you will find a lot. PCB based kits are the easiest to build. You don't have to read a schematic to assemble.
