    Hey Fellas: Curious if it would be possible to install a pre out into my Sunn 1200S (old version) head. I'm sure someone here could take a quick glance at the schematic below and give me a sure yay or nay. Regards.

    Yes it can be done, but by a good tube amp tech as it would need to be isolated from high voltage DC then it's level adjusted for normal line level.
