[Yaesu] FT-5100 Schematic - 100 Pages?

[Doc]

I am trying to repair an audio problem in my FT-5100. 
We tried swapping in a different mic and it did the same 
thing but both mics worked perfectly on a different Yaesu
rig.

The ARRL Technical Specialist assisting me asked me to 
get him a schematic so I looked on the Internet.  I found 
a 2.2 mb file on many sites, including 
http://krasnodar.online.ru/hamradio/sch_eng.html  but the 
problem is it opens up as a .bmp that is 100+ pages long!

I tried shrinking it but could only get down to about 60 
pages before too much detail was lost.

Help?

Thanks! & 73, Doc  KD4E
