Howdy,
Some of you may recall that I built a 2204 clone from an old amp chassis that had I kept in the shed for the past 40 years. Well, in my search for other circuits I have stumbled across the info on the original beast that became my 2204 clone. It was in a former life a ETI Playmaster PM116 giving a very clean 40W using a pair of 6DQ6's

When I got it my amp had been modified to use 6L6's, and after the 2204 rebuild I changed it so that it now uses EL34's. I am seriously looking at rebuilding again back to 6L6's although a full restoration back to original 6DQ6's is not off the cards.
For those who are interested our Aussie amp building hobbyists at the now defunct electronics magazine ETI did venture into wild territory, such as a Tube based 140W monster called the Playmaster 456 - Rocker ... A brute of an amp with nil tone stack, one volume control & some on/off switches.... Just what's needed for those special non-guitar loving neighbours...

I'm sure the site has other treasures of Aussie tube history...
