Interface Electronics Stevenson Series 100 Mixer Mod 8x4 with Manual & Case 1972

Description

Extremely rare vintage circa 1972 Interface Electronics Stevenson Series 100 Mod 8x4 analog mixing console.
Unearthed this beauty from a local professional studio, complete with original case and manual.
Tried to include as many photos as possible to create a detailed thorough listing, the unit has seen better days as one can see. It looks like the original owner removed or was in the process of replacing those 3 model 100 AP/ts.
Needs to go to a good home of one who would appreciate such a vintage unit.
In full disclosure I am unable to attest to the functionality of the unit as I lack the required equipment and knowledge... Though I can say the owner took exceptional care of his gear. His name is etched into the side, though this can be scratched out.
Happy to answer any questions I am able to about the unit.
