Thanks for the helpful replies.I have attached a photo of the 6 coils and trimmers.I have identified the LW coils as the 2 on the left upper /lower,Mw in the middle ...Some fine tuning did not improve Lw but bought in some weak stations on MW(eg603Khz R4 from Eire).I still need the extra long aerial ;am I right in thinking this should not be necessary
I visited my locla library to see the Ace circuit which is Not identical but has same valve line up and chassis .However coils are different.Also mine does not have the IF aerial stopper as mentioned earlier in this thread.
ps the tuner is 2 gang.
