DESPERATELY searching for a 1969 Sunn 1200S shematic.

I'm trying to fully restore a 1969 Sunn 1200S and it's very difficult without a schematic because I can only find one for the 1970 1200S with the solid state rectifier. If anyone can help it would be much appreciated. Thanks

So you want a 1969 1200S schematic which would have Reverb, Tremolo, Mid Boost and tube rectifiers. Does your amp have the extra filter cap, usually 20@600V, or just the 525V rated four section can cap?

Here's one. Uhmmm... Are YOU trying to do the restoration, or are you having a tech do it for you?
No offense intended, but based on your previous questions about impedance and speakers you should probably have an experienced tech actually do the work.
There are potentially lethal voltages in that amp; and if you are doing a complete restoration with the intention of using the amp regularly it will likely require some "outside the box" engineering to actually pull it off.
