Sorry to drag this up again but I have the same problem with my EA12.
It looks to me like the fault is in the RF amp (v1) although this valve is good.
The cathode of V1 connects to the muting circuit, so check the standby switch contacts and also the crystal switch. If I connect an aerial to pin 1 of the valve socket via a DC blocking cap I get reasonable performance.
Also checking c32 for a short.
