I Have checked the aerial coils L5 and L6 and just for good measure I also checked both I.F transformers. I have rechecked the capacitors that I have replaced. I have also checked R10 and all the earth points checking they have a good connection. I have also slightly repositioned C18 to ensure the replacement is in the same place as the original.
I cannot get any interaction between this set and another when tuning either set.
I have rechecked the valve holders and put a little more contact cleaner into V1 holder and worked the valve in and out a few times.
The burst of oscillation is harder to recreate now but I still have no reception.
I will attach some pictures of the replacement parts etc.
Please excuse the tacked in electrolytic it is all I have at the moment. I will replace it with an axel type when I get some.
Thanks for the help so far it is much appreciated! I do have a gallon of petrol and a match somewhere if all else fails!
Rich.
