“Just to say how pleased I am with the Double Six build and the parts I had from you. I made it more difficult for a first amp build than I need have done by making my own chassis from a sheet of alloy and adapting your amp to fit into a tweed chassis. Amazingly it fired up first time….virtually all the parts were from you except valves and a few small bits. This is an excellent design with huge cleans and very loud especially if you fit a 101.8dB/W speaker!! Yet the power scaling is perfect for practice, I never open it right up even on 1 watt.
“Interestingly, you have created a very environmentally friendly amp – I measured it using just 140mA at idle on the lowest setting and just for fun ran it on a solar panel which it did easily. Just a couple of little blanking panels to fit at either end of the chassis and some little support brackets underneath. Very impressed with the design, to achieve such great sound and volume with only 3 valves is superb, fat switch and boost very useful too.”
