I was curious about this design and so I did a bit more rummaging through my old valve data books and I came across Mullard's Valve & Service Reference Manual (2nd edn 1951). Sure enough, in the back of that is a multi-purpose circuit for a 10W or 30W amplifier with separate component lists for the two powers. I never realised that it was there, so thanks for that

.

Attached are scans of the circuit and the component list for the 30W option. Is this the amp we're discussing ? Compared with the level of detail that Mullard go into in their Circuits for Audio Amplifiers just a few years later the description here is very, um, terse. This is literally all there is.

Cheers,

GJ
