Howdy,
I've promised a friend of mine some pictures of the inside of my Spectrum I in the next week or so. The circuit is very much like most of the earlier Sunn amps, and I'm sure the layout is practically identical as a 200S (looking at various early Sunn's you'll see that whether they are 60w or 40w models the respective tubes are in the same places).
Let me know if you'd like me to send you copies when I take them, I'll be happy to do so.
