Hi
Looking closely at the circuit a germanium Diode won't work as it stands and in fact doesn't. Its bias is too high. I replaced the transistor with a 1SJ150, and this works better with less distortion. I've added a 3.5mm mono switchable socket, the radio actually sounds good on an extension speaker.
