Regarding Tracks 1, 3, 6, 7, 8 & 9:
These stereo mixes were recorded using an at the time new technology called the Haeco-CSG "Compatible Mono/Stereo" Process.
The idea behind HAECO-CSG was to create stereo records which when played on monaural equipment would "fold-down" properly to mono.
CSG basically leaves the sound of the individual channels intact but shifts the phase of the right channel with 90 degrees, so when folding the two channels together all elements that are mixed in the centre (vocals, drums) aren't doubled in volume as opposed to anything that isn't panned in the centre.
When played in stereo, it results in a less definable panorama and a volume decrease of all elements in the centre as opposed to everything that is panned sideways.
-Right channel inverted (180 degrees polarity switch)
-Another 90 degrees switch to right channel with Voxengo PHA-797
-3 samples removed from right channel at the beginning of each track to bring them exactly in sync.
Those adjustments were made by ear and eye (in that order). No channel re-balancing was done. The vocals and lead guitar are now (almost perfectly) balanced within the center of the stereo spectrum, as it should be. I believe this is about as good as it gets. Not to mention that no official release has yet managed to completely correct this flaw.
Enjoy this fine Dr. Robert Rip.
