[QuadList] OT Going though the manuals--Dupes may be different versions

[COURYHOUSE at aol.com]

Right on Ted! Good  to bring up! The Sony stuff in particular   seems to 
have   thank s at at  first seem to be a double   but reallyis not..
 
I learned my lesson last year when  we  got that other  manual stash.   I  
am  paying  real  close  attention to all publication data...You have to be 
really careful    indeed  when sorting.
 
In  this  case  I think there was a work  copy and  a  file  copy.. as  you 
can tell there is a difference in amount  of usage... not  to  say  one is  
trashed... but   you  can just tell it was handled a bit more.
Ed!

Hi, Ed,


Some of the "dupes" may prove to be different editions.  Sony notes  their 
editions as "revised" such and such.


So you may find, say, a BVH-2000 manual set—Volume 1 and 2, Revise 1 for  
Serial numbers 10000 to 12,283.


And then you might run across another set revised 12 for 10000 through  
14673.



Generally, The newer edition will have newer boards, design and service  
procedure info, and may have different part information.



KEEP BOTH. Especially if there are engineers notes in the older  ones.
