notes:

First of all, this copy like confirms me there are a lotta different copies of this recorder, all missing/including little pieces of it, it's like the taper copied it differently time by time to track the traders.
This is the longest copy I've ever checked anyway.
These are the main differences between this copy and the legitimate 1st generation tape I got:
1. This version has a long soundscape intro missing completely in other versions.
2. There are few seconds of the beginning of Pigs edited out from this copy, the 1st gen has some seconds of the beginning of Pigs that I didn't notice in any other copy around (they are still few seconds only anyway)
3. Speed is too fast at times, above all during Pigs! This in almost all the copies and I guess on the master too, though on the 1st gen the speed problems are not so evident like on this one for example. Also here Pigs is not spit in 2 parts; Pigs is spit in 2 parts in few copies ony (included the 1st gen)
4. Welcome To The Machine has not the little edit at the beginning present on the 1st gen (and few other copies only).
5. Have A Cigar has no edits here, on the 1st gen there's a little edit at the beginning, whereas on this copy you can hear the tape stops at the end of WTTM and begins again on HAC but there's no missing portion (there's rather a little repetition of few secs.; probably the songs were on the 2 sides of this tape copy), again, also about this that little edit at the beginning is on the 1st gen I got (and few other copies only).
6. There's a little stop between HAC and Whish You Where Here on the 1st gen, on this version it's consequential (no stops) like in other copies
7. evident speed problems at the end to SOYCD 6-9 on this version! (full of distortions) but here it is complete! 100%; the end of SOYCD 6-9 was edited out from the 1st gen maybe right for this problem, it was edited out in almost all the copies I heard before too!, so in spite of the distortions I know now it isn't really cut on the master at least..
8. Both the encores have little more audience applauses, on the 1st gen those are shorter.
about the sound:
this sounds pretty differently from the other versions I got, included the legitimate 1st generation tape. There's much more instrument definition here!; but it was maybe transferred at a too loud volume and this provoked some evident crackles at times, I think a bit of post-processing have been applied on this transfer to smooth the crackles.
Also some transitions between tracks have tics due to the burning, but these are easily removable (not a problem or flaw at all).
Overall this is a very nice upgrade to me.
with many thanks to T!.
