I've got a Heidleburg which worked fine 'til about a month ago.  Other than the
speaker connections, I only have one row: - 1) (big male), 2) + (big male), 3)
'sun or light symbol' (small male), and  4) 'Y superimposed on an I' (small
male).  The first goes to ground, the second goes to power switched or
unswitched, the third, I believe, is for the radio light, and the forth is,
again I believe, for the power antenna.
