My wife purchased these speakers at a garage sale and of course didn't
get the power supply. Radio Shack has a 12volt/1Amp replacement. I've
got the plug narrowed down to Radio Shack's "M", but need to know the
polarity of the speakers. It isn't stamped anywhere on them. I assume
it is - ---C •--- +. If anyone has these speakers can you confirm this
for me?
Thanks for your help.

rereading favorite books has always been one of the quasi-
religious ceremonies with which I occupy my life.
