It's Alive!

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I finally completed a proof of concept for a really snarky-looking headphone amplifier tonight. This idea has been rattling around in my head for more than a year, but other projects have delayed it until now. I'm using the 6SL7/6SN7 combo in the "Frequency Compensation" thread below to drive a pre-WWII dual triode. The triode includes two "mouse-ear" anode connections on top, and they're both grounded to the chassis behind the tube. That means you can walk over to the amplifier while it's playing music and actually grab hold of the anodes. No shock, no buzz, nothing. Really, it's crazy. Output power is about 0.6W, plenty for phones. Can't wait to get both channels done and rebuild it in a real chassis. Wow, this is just too much fun! I gotta go touch it again...
