I'm also surprised that more people haven't taken an interest in this.
In the days before VCRs this WAS Star Wars for most people in the 70s and early 80s - it was the only way they could relive the movie (unless they were incredibly rich and could afford a 16mm print). I still know the narration by heart!
These albums ARE my childhood and I'll always have a great big soft spot for them.
I do have the facilities to transfer these LPs from vinyl though to be honest, if I'm going to create an audiophile version, I'd rather use a better turntable (I have a bog-standard USB turntable from an unknown German company - DJTech). That said, I can do some tests and see what comes out...
