A good point. The 8/II does indeed use the transformer for 2.5, 10 and 25v AC whereas the 8/III only uses the transformer for 2.5vAC. (There's a small capacitor across the 2.5v resistor also)

It seems they did take a thoroughly holistic approach to improvement, that is to say the difference between MkII and MkIII is not what i initially thought, ie just an extra fuse and more windings superceded by component resistors!
