My brother Dr. David Martin picked these up for me on Christmas from an estate sale on eBay and I could not believe the condition, they are from 1973 and have my initials MM on Quality Control. They are a 2 way with an 8 inch yellow cloth surround and a 2 inch paper cone phenolic ring tweeter. Real simple but sound real sweet. They were replaced by the Gamma 208 in the 70's.
I wanted to mention that my son Jared Martin had a music class at Lealman Middle School in St. Petersburg Florida only to find this model and they listened to Bach, Beethoven and Mozart on them..
