Yes. The octal socket on the back is designed to allow the radio to be
operated from a vibrator power pack, and for AC operation a plug with
one or possibly two jumpers is required. Unfortunately I don't have the
information on which pins need to be jumped handy -- I'm sure someone
will come up with that information.

You need two jumpers. One between pins 3 & 4 and one between pins 6 &
7. --Ed
