:I've found several small resistors that appear to be wire wound that are open around the wafer switches. They are small indeed, does the same colour coding apply to these? I like to double check the circuit with the colours. These are tiny resistors.

::I will try those settings. One thing I have noticed is that the cathodes on tubes 6BJ6 (V5 and V6) are running high, 11 and 6 volts respectively. I have changed most of the capacitors around those tubes, am I looking at a short somewhere that is drawing them up?

::::I have a National NC-303 from which I can pick up ssb but cannot pick up anything on AM mode. No movement on s-meter. Essentially have RF gain but no audio gain. Can someone point me to avc cirucit in this radio in terms of troublshooting components? I have tracked avc line from accesory socket back to V1 and it checks OK.
