Tubes!

Laurel Amp

I'm a big fan of tube amps. Here's a picture of a tube amp I built from a kit about four years ago: a Welborne Labs Laurel. The Laurel is a monoblock amp that uses a single 300B triode (three element) tube. The 300B tube (the large tube with the white base in the back) was developed in about 1936 and puts out all of 8 Watts.
