SB1400 A SPINNER KNOB FOR THE HEATHKIT SB-1400 TRANSCEIVER Many of the newer pieces of equipment do not have a spinner knob. Remove the wide rubber band from the knob to expose its Allen-head setscrew. Remove the knob and replace it with a RADIOKIT PS-210FSP spinner knob. The shaft hole in the new knob is 1/64 inch larger than the removed, but it is easily shimmed with a paper clipping from the cover of a QST magazine. RADIOKIT, PO Box 973, Pelham, NH 03076, USA.
