model CXNA508 I have no Service Manual. When Powered on,a slight hiss can be heard in the Left Channel. Then Power will kick off. I can see the Base Volages on the Left Outputs is wrong. Left Channel Base Voltages,3-5v Right Channel Base Voltages, .6v I've swapped outputs,but problem stayed in Left Channel. There is a small Transistor(stamped CC 5551) in each channel that I swapped also,to no avail. I resoldered PCB. Neither CD nor Tape are causing the problem,as I have disconnected both. Found no bad caps,even the SM Transistors in the Output area check OK. Cleaned Volume Control. My problem is I can't trace these Base Voltages back. Any Help out there ???
