Marantz 2220B bad J812 and J808 Voltage

The KSC945 I purchased and installed did not have the “C” suffix and doesn’t have a C middle pin.

Could I just switch the Pins on my board?
 
Yep. You can bend the pins to make it work. Just make sure the bent pins are insulated from touching each other. And hope it hasn’t been damaged from being installed incorrectly. If you have a fresh spare I’d use that.
 
Yes the receiver works now. I appreciate all the help. The original issue when I got the receiver was that it made garbage sounds and stopped playing altogether after a couple minutes. I measured 0V at J808 and rBuckner helped me then. I replaced what could have been bad i.e. H807, H805, H806, R803 and R804, and ended up installing H806 incorrectly. I adjusted the pins the receiver works.

I set the J812 voltage at 35VDC as well as bias and output voltages at the recommended values.

She sounds great.
