Thanks Bill. May be the next thing I will try. This seems to put the volume control in the output circuit where later models have them.

I made the changes in your diagram to my delight! Grounding the receiver was not an option for me. With the circuitry change I can now control the volume from zero to loud on the strongest stations. I do not notice any distortion at any volume level and I now receive more stations than I did before the changes. Amazing! Thanks much!

If you would like to raise the sensitivity that 1.2k resistor seem a bit low unless you have a 50,000w AM blowtorch near. The original was 20k. I'd play with that value. Try 5,10,15K. If you live in stickville you can just remove that resistor.
