I'm currently working on a HMV N2-22 and I cannot find a circut anywhere.

What is the electronic difference between N2-22 and N2-66?

I have the schematic and notes for the N2 chassis. Valve line-up is 6AN7 6N8 12AX7 6M5 6M5 which appears to be the same as N2-66 on Kevin Chant's site.

According to Radiomuseum, the N2-22 is a wooden case with legs and the N2-66 is a fabric covered table top case available in blue, tan or grey.

They both appear to use the same chassis, N2, so my guess is they are electrically identical.

Not quite, It appears the N2-22 has extra control circuits, and probably slightly different speakers.
Otherwise electrically identical.
