Default Re: ECC83 and Germanium diode to replace 7C6

I did a similar fix once on an old Murphy - the octal-based rectifier had failed, and in such an old set I didn't want to subject the smoothing capacitors to the high HT voltage from s.s. diodes during warm-up of the rest of the set. I simply removed the octal base from the old valve, soldered into the hollow pins some 2.5mm cores stripped from some T&E, sleeved them and wired them to the appropriate pins on a B9A holder for an EZ80 to sit in. The finished structure was very rigid and stable, though not quite as neat as Electronpusher's
