Hi Steve,

You don't mention which version of the R200 you have; there were three - plus a few changes to the circuit specs within those three main variants. The early ones used OCxx transistors and the little cap you mentioned should indeed be 40pf. Later versions used AFxxx transistors and the cap in these was IIRC 20pf.

Have you tried the simple expedient of shifting the LW coil along the ferrite rod aerial ? Often these coils shift and/or the ferrite rod becomes cracked because careless people tend to remove the chassis by pulling on the aerial rod.

Regarding strong stations, this depends on where you live with regard to MW, but on LW BBC R4 is fairly good regardless of location or if you live in the west of England or Western Scotland RTE 1 towards the high frequency end of LW is a good signal.
