If you want to use tubes as your amp, you'll need to run 240v or more through them to make em sing. and then you'll need multiple transformers with multiple taps on each, for input as well as the output. Plus you have to pay a lot of attention to wiring locations and placement to reduce/eliminate noise.... yadda yadda
and yeah, transformers are pretty much always a major bulk of the expense.
So, if you just want a decent sounding amp project, you might wanna stick with solid state. There are some really nice projects out there that will be nicer to your wallet and still reward you with hi-fidelity sound.
