Finished the re-capping today and tested the set. Radio and turntable working well. Just one helluva mains hum which is present despite the position of the volume knob. The service sheet makes mention of mains hum and suggested remedies (bottom of page 2), which I have done, to no avail. The set is missing one ECL82 output valve and I'm wondering if this is contributing to the hum (distortion?) One is on it's way tomorrow, so we shall see....
