Hello,

Leon has indicated that the 10C1 valve may in fact be OK (see other thread).

So I am not sure where to go next. The AGC decoupling capacitors have been replaced and the resistors measure OK.

The background 'noise' on FM is nearly non-existent, but on switching to AM it is obvious that something is not right. With a strong aerial signal and by tuning exactly to a station, the noise becomes (almost) unnoticeable, but it is very evident between stations (especially on LW).
