Calvins Bristol 20 ended up being the most compact head I have built to date measuring 20 x 8 x 9 and weighing in at only 23.4 Lbs. It utilizes Heyboer transformers, Sprague and F&T capacitors, Vishay Dale and Allen Bradley resistors, Belkin sockets and retainers, Belden wire, and JJ tubes throughout. The cabinet came from my new builder and you should see more non-traditional, interesting sizes and styles coming soon.
