Hello, I have the radio discribed. Someone has tweaked it prior to me getting it and I would like to turn the power down a little. The board on this site and the board in the unit are not the same but the power and other adjustments are not the same as I was told. I don't know which board it has for sure. The only number on the board is PC-159AA.
Any help would be greatly appreciated.

Re: Board in my old Courier Spartan PLL 40CH
I think that I only have one set of diagrams for a spartan, I do not know if it is the same as yours, as they do not have the PCB number marked, but it is for a uPD858 PLL, so it may be the same one.
According to the diagram AM power is VR6, so if that matches up then it will likely be the right diagram (let me know so I can mark it with the PCB number).
VR7 is the ALC (SSB Limiter) and VR8 is the AMC (AM Limiter).

Just in case anyone else has or finds one of these old Couier Spartans this one does have the UPD858 and the adjustments for power,ssb and mod are as Scott said in his reply. For an old radio they kick some serious butt. Better than alot of newer ones.
Thanks Again!!
