I got my 600XL working last night...

Just for fun last night, I decided to do a chip swap between my dead 600XL and my 800XL. The first chip I tried was the 6502. Then, I popped in Space Invaders on the 600XL and to my surprise, it worked! However, there's still one issue I couldn't fix: The sound was dead. I tried swapping POKEYs, but to no avail. Can anyone help me here?

Well,

 

If Pokey is doing ok (joysticks work ok?) - Then something isnt getting to the cable that feeds the TV - Can you check the monitor port output to see if sound comes out there?

Yes, the joystick ports work fine. I know the cable is good, it works fine on my 800XL. BTW, the 600XL has no monitor port.
