I have just acquired the following heathkit equipment and would be grateful if someone could supply me with original or copies of the manuals. E-copies OK. I will be happy to pay reasonable cost. SB-650 Digital Frequency Display. PS-1144 Power Supply for the SB-104A I have checked BAMA and there is nothing for either the SB-650 or the PS-1144. 73, David KB3GJH
