It does make a note about
selecting the right position for the mic type switch which appears to
provide power for suitable electret types. If your mic has a built in
battery then I would recommend setting this switch to the dyn position to
avoid sending power to it.

Interesting. Since the 66B is, so far as I know, a condenser (it certainly
has an internal double AA battery driving it), I just assumed I should set
the R-1 to Condenser rather than Dynamic. But that sounds like an
interesting idea so I'll try it. Thanks.

Cheers,
