[78-L] fake stereo

[Randy Watts]

Some rechanneled stereo folds down to mono reasonably well and some doesn't. If all they did was emphasize the treble in one channel and the bass in other, you can often get listenable results, albeit usually with extra reverb. Other processes--not so much. Capitol's "Duophonic" process is pretty much hopeless. At least I've never been able to get the things to sound like mono. Same with RCA Victor's process.

This is not quite on topic, but I'm sure there are plenty of people who can give some information/advice. 
   I'm interested in restoring an 'electronic stereo' disc to decent mono sound; clearly I need to reverse whatever original processing was applied, if possible, but I don't know what that would have been. Were there different approaches? Can anyone advise how I can go about investigating this?
Thanks,
Chris
