I picked up a Rowe CD 100C. I thought it was working when I bought it but now I do not have sound on the left side. I reversed the RCA's from the player to make sure there was a signal and there was. I also removed the amp and switched the left and right driver boards and I still only have the right side. Power transistors on the heat sink all test out the same. Sould I be looking somewhere else or is there a problem with the amp board? Thanks
 
Check to see the 13 pin flat white wafer jumper on the amplifier is inserted correctly (correct orientation and fully plugged in). Look for cold solder joints on the preamp board, especially at the connectors.

Look at the output transformer terminal strip to be sure the jukebox internal speakers are connected correctly.

Check the volume control metal jumper on the volume control terminal strip to be sure it's in the correct position and that both screws are tight.

Lastly, check the speaker crossover network circuit board located in the amplifier compartment. It's bolted to the right side wall. Flip it over and look for cold solder joints on the connector header pins.
 
Thanks Ken. Yep it ended up that my jumper wire on the volume control terminal strip was not connected properly. Works great now!
