This is a modified Williamson (adjust bias and balance). I've built 3 of them; for myself and my 2 sons. The rack mounted version goes with my son's recording studio. The other two are the usual chassis-mount. Transformers are from Hammond and tube lineup: 12AU7's and 6L6's.

Transformer enclosure is flat sheets of aluminum, assembled with JB Weld.
