Which of the two channels is working now? What happens when you temporarily connect points "F" and "K" to each other? By doing so both channels of the amplifier section will see the same input voltage.

Hello Robert
Thankyou for your reply, you are correct with the Cartridge output...I must have misread 430mV for 43mV !
As you say the radio output signal Voltage must be similar to the Cartridge/Turntable output..I attempted to measure the radio output with a DVM.. may have not been at all accurate. Thankyou for making me think more about it...Both the Radio and Turntable connect directly to the exact same Amplifier circuitry..so they must have similar outputs.
Currently trying to work out why I have bad hum on the right channel.
