Default Re: NAAFI receiver problem

I have just checked the diagram. Measure the voltage on the control grid of the mixer. If it is positive C14 could be leaky.
R10 could be open circuit, in which case connecting the meter to the control grid of the mixer will cause a reduction in the cathode voltage.
