Hi guy's

For the schematics and part list pls look at post #10 and #11.
I have not included R1, C1 and C2 on the PCB as they are on the connector and in between the connector and the PCB in my setup.

Also changed R17 and R18 into 2 parallel resistors as I use a reed contact to switch the Iq and dont want to take the risk that this currentpath gets interupted with the result that the Iq is undefined.

Let me know if there are any other questions

Thanks!
