The ervice manual for my 1982 Kenwood KR-1000 receiver is great! Full detail on all circuits with part number detail. I will definately be ordering more manuals for my other vintage equipment! Order was fulfilled quickly! Very efficient ordering process! Thnaks for your help! Great site!

Everything in the manual was excellent except for a couple of pictures of specific areas in the unit that were a little dark. Owners Manuals re-sent the pdf file & the problem was corrected. Excellent product! George
