Maybe one of the transistor's biasing network is at fault. I'll assume
the transistors are biased class A, which means the collector voltage
(assuming common emitter circuit) should be at about 1/2 of the supply
voltage. It sounds like one of them might have the collector voltage
running below 1/2 of Vcc. Check the resistor values with an ohmmeter.
Transistors are usually the last thing to replace...

Thanks for the Schematic link.

The D104 is connected to the Oscope and terminated into a 100K
resistor. It is not connected to the radio so RF is out.

The Oscope shows clipping on the negative peaks, the postive peaks are
OK.

I tried removing the battery and powering off a power supply where I
could vary the voltage to see if the distortion disappeared with
voltage, it did not. The affect was a lower audio output.

the best thing to do is to replace the two NPN and see what happens.
