Re: Vidor CN429 'Lady Margaret' fell silent
Is this on both pins of the primary of the O/P transformer?
Disconnect the speaker and go across the secondary of the O/P transformer with your Ohmeter. There should be a reading there.
The valves are in parallel, so they should all have 1.5 volts on them.
Check the voltages on the valves, especially the Output. There should be two pins linked to the Output Transformer (Pins 2 and 6) and Pin 4 should go straight to the HT rail.
Cheers,
Steve P.
