Subject: Audible rotor direction indicator


>I don't think I have commented on this thread, but back in 1975,

> under glass and probably had a very small needle.  A friend at

> oscillator with a pointer knob on top that rotated freely 360
> degrees.  I would set the pointer in the direction I wanted to
