Pity we can't make our own triodes eh!
Philosophers have only interpreted the world - the point, however, is to change it. No it isn't ... maybe we should leave it alone for a while.

I just found it of my own volition and was about to post it here when I see Ray linked it already. 2 steps behind again! Cool though.

Yes! For a change! :D

Now I want to know what it's like with proper decent passives, kosher gapped TX's and a better sound source! (AM portable? Really?)

Well, there you go then Mike, a recuperation project for you. And, if you build two you can have stereo, whatever next!

Doubt if you will have anything close to stereo. The valves will be far from matched, and I doubt a better transformer would make up for running the valves close to 0v bias with a coupling cap. It would have been very interesting to get some characteristic curves for the valves though. Very interesting none the less and clearly more effort has been put into making the valves than the rest of the project.
