The schematic I have is from nostalgia air (http://www.nostalgiaair.org/Resources/480/M0001480.htm) and has a lot of voltages listed but these were taken with some old voltmeter that loaded the circuit so they are only so good. There is nothing about volume setting or signal level. I do understand that the volume control should reduce the gain of the circuit. And as it stands there seems to be too much change in voltage and bias. So without any point of reference where to start?. The voltage divider of the power supply is fine. And of course I changed almost all the capacitors' checked the continuity of the coils and all checks good. There is a double layer of windings on the oscillator coil with some sort of insulator in between but it looks good no green stuff.
