I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks
