Hello list,

does any of you gentlemen posess a service manual for John Fluke's 825AR 
differential voltmeter? I got one together with a 801BR, and as the 801 
is almost cured now which was some fun, i prepare to look into the other 
patient whose state is worse. The 825 seems to have the same power 
supply as the 801 and similar KVD and switching. However, the null 
detector is very different.

(The center-zero instrument is stuck and the chopper is silent, so if i 
can't revive it as a diffvm, it will at least give a nice 
calibrator/voltage source.)

best regards,
