Tube equipment is badass!! About 10 years ago, I was suffering from a lack of creativity. So, I got it in my mind that I wanted to build a Vacuum Tube Amplifier. My brother-in law's brother is an electronic genius, so I had him modify plans from an existing one to suit my needs. It is ON/OFF, and volume only - no other adjustments. It is point-to point wiring, built on an aluminum backplane, with a black walnut & spanish cedar case. To be honest, I do not recall how many watts. Around 25 or so, but it drives the Yamaha speakers I have attached to it nicely.
