Spencer's input is basically correct but some of the numbers are jumbled up a bit. I have a Mk3 unit as well.
Phono section info is exactly correct.
Line section: V6, V7 & V10: 6922
V8, V9: 12AX7 &
I believe that the Mk2 used to use 12AU7 instead of the 6922. This was a noisier tube & the Mk2, for some reason, "ate" these 12AU7 tubes rather quickly. (Maybe they were biased too high?)
Also, hope that Ken S. will see this thread & maybe give us his inputs.
