Pursuing a case of poor sensitivity in one of these receivers we tried the effect of realignment. The result was quite good on M.W. and L.W, with the exception of a section on the M.W. band between 250 and 300 metres, where really serious instability occurred.

Further checking revealed that a fixed tuning capacitor connected across the primary winding of the first i.f. transformer (C2 on Trader sheet 1098) was open circuit and a replacement cleared up the trouble entirely.
