Yep. It's a 470 ohm resistor across pins 5 and 6. Ron AC7AC K2 # 1289 -----Original Message----- ... I have a broken resistor pack.... Its the red coloured RP5, 470, 10pins (10A3.471G) part on the control board. It's broken between pins5 and 6. It's in two pieces. Does anyone know whether there is any connection between pins 5 and 6? I've emailed parts@elecraft for a replacement. Cheers, Dave.
