I see it uses a crystal earpiece, I wonder if there is a resistor across it, 20 to 100k does make a noticeable improvement in sound level. This stops the earpiece merrily charging up solely relying upon the leakage of the diode and earpiece to discharge. There is a "Works" in Maidenhead, I might get one.

The silicon junction diode cockup is probably because of a "buyer" being in charge. Has anyone told "Works"? I will if I get a silicon junction diode.
