Notes

KB service note;
The models OP21A & PP31A are similar to the OP21 & PP31 but fitted with Car aerial socket with additional winding on ferrite rod. Incidentally, this rod aerial assembly was used as a replacement item for all four models, the car aerial winding should be left disconnected when used in OP21 and PP31.
