I am more confused than ever! I have the 4.7nF capacitors which are small and have no polarity marked on them.
I think I should be using an electrolytic capacitor attaching the positive end to the cathode of the output valve and the other end to earth.
The manufacturers picture shows a big fat thing whereas my capacitors are wee 5p sized things. C46 on the diagram.
Does the polarity not matter? Can I use one of my little 4.7F capacitors or should I get another from the internet?
The other thing worrying me is where PW Drive mentions a capacitor with polarity 'C56' . That one is not on my diagram but maybe you mean C46?
Sorry to be such a pain.
You will all be pleased to know that an old Sansui Amplifier AU70 - its R channnel has gone dead so I drove over to Glasgow yesterday and gave it to a chap to look at - he said he could fix it. So both you all and I have been spared a much more complex problem! Lindsay
