Out of interest, I tried disconnecting C9 to see what happens - and the set still works but the output level drops by a large amount, so C9 is doing something good whatever it is....! I should add that it's not floating; the supressor is connected to cathode as in the corrected schematic. I'm still amazed how well this ancient little thing works on MW bringing in 5 station loud and clear. Just been listening to smooth radio no problem at all.
