Thank you! I just downloaded it, and that is what I was looking for. My HP105B is showing strange symptom. OVEN meter reading is always at full scale and frequency tends to wander. This will certainly help. Thank you again.

What I have is a 39-page document of "Manual Updating Changes" dated April 5, 1989 that covers the update ("This supplement adapts your manual to instruments with serial numbers prefixed through 2848A."). It has schematics. This is available at ko4bb.com as a .zip file, somewhat confusingly named "HP 105B Crystal Oscillator Service Manual-HP105B PSU.zip." Visit the "manuals" page <http://www.ko4bb.com/getsimple/index.php?id=manuals> and search for "hp105" (do not type the quotation marks). The .zip file contains two files, 37 pages of text plus 2 pages of full-size schematics.
