Ok, I've located the fault. First off, I checked the valve voltages and they all seemed there or thereabouts. I tried my ipod via the gram socket and the sound was shockingly good. So, as I surmised earlier, it's definitely a front end problem. I decided to check resistances of the remaining 'coils in cans' ie the ones that have not already been identified as faulty and rewound. Sure enough L13 (trader sheet) is open circuit. As yet I haven't gone through the relatively long process of removing connecting wires from the can and obviously, not accessed the coil itself to see if the break is somewhere where I can repair it. If it isn't, I'll be knocking on dear old Mike Barker's door again (third time on this set). This is definitely the 'faultiest' set I have ever worked on. We'll get there.
