Probably under a Benjamin...the transformers would be the most expensive part.

Umm...it...amplifies? Not really sure what you mean, you mean how tubes work in general?

Good power/output transformers are always going to be the most expensive parts on these sorts of things...because otherwise, you'd just be listening to 60Hz rectified AC :) The trannys often determine the frequency response and overall sound, so you need good ones. The ones that he used for that were Sowters, which are UK-built trannys of high quality. Might be over $100 in just those parts. US-made ones that are decent include Hammond, Magnaquest and Electra-Print.

Everything else is cake, though...wire is cheap, the caps are cheap, and those tubes aren't as expensive as you might think. Less if you don't need really rare NOS varities, like were shown.

No not how amplifiers work.

I mean do I plug it into say my mp3 player then the headphones from that?

Or is it HT use only?
