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
.
It looks like the original owner removed or was in the process of replacing those 3 model 100 AP/ts
, included.
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.
It does look like it needs some work.
I can say the owner took exceptional care of his gear. His name is etched into the side, though this can be scratched out.
Other functioning units in this series have been known to sell for over ,000
Happy to answer any questions I am able to about the unit
or provide diagrams from the manual.
