Doing something I should have not done , I managed to blow up Q11on the control board. I fixed that with a replacement from my junkbox. All voltages are correct on control board U3. When tapping display I get a voltage of 23.3 volts indicated from a 12 volt supply and zero current. Further checking shows R7 on the control board is zero ohms instead of 1.78K. How important is it to replace R7 with a 1% resistor rather than something from the junkbox? Everything else on the K2 works fine , TX and RX are OK. Hopefully a replacement R7 will then display the correct voltage and current. Any input from the reflector is appreciated.
