2 Stroke Updates

Hi there,

I decided to build a 2 Stroke amp as an intro to valve amps after reading Dave Hunters’ “Updated and Revised Edition” book. Buying a kit wasn’t really an option in the UK, so I sourced everything myself, got a schematic off the net and built the thing. Few design headaches along the way, but after some creative thinking, everything was sorted, it was built, and is working fine. I gave it to my son as a birthday present. he loves it.
However……………
Wanting to use other valves as it should be capable of, I became aware that after this “revised” design, such as dropping to one power valve, there were other changes to the design, which folks refer to in numerous forums. What I could do with knowing is, is there anywhere that any, or all of these changes are available to view, or is that info only available to folks who have bought a kit?

Cheers
