This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)

I was very pleased with the service provided and was surprised at how good the quality was of the manual. I thought it may be a third generation copy or so, but it is as good as the websites that charge 3 times this much. I repair some electronics for family and friends without charge, so this is perfect for me. Thank you very much.

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

Additional Service Notes/Revisions
Customers who complain of a low level distortion heard only during very quiet musical passages, or experience erratic/inconsistent turn-on performance may need to have their units modified as follows: 1. Remove jumper wire JW12. 2. Change resistor R24 to a 22k ohm, 5%, 1/8W. (JBL part# HM185-02202-00). 3. Change capacitor C19 to a .0047 uf cap. (JBL part# 3679472120). 4. Cut trace at SW1 (middle pin which runs to JW12). 5. Add 2" insulated jumper wire from SW1 (middle pin) to right-hand side of JW12. Route this jumper away from the four large diodes. 6. Add an uninsulated jumper from the left-hand side of JW12 to the ground trace which runs just to the right of it. Serial numbers below should already be modified.
100v 120v 230v
NOTE: If a customer (of a later revision) is insistent that the auto-mute feature work on his subwoofer, an easy way to accomplish this is to use the speaker level (high level) inputs on the unit in lieu of the RCA jacks.
WIRING DIAGRAM

JSEKD13486 and above JSELD027239 and above
JSEKF20034 and above JSELF020498 and above
Early versions of the units ending with serial #JSELD 024124 had a 18VDC output jack; later versions are missing this. It's presence or absence does not affect subwoofer operation in any way.
Early versions of the units below serial # JSELD 024125 will cycle into a standby mode when the signal source is absent after a predetermined time; the green LED turns OFF when this happens on the 120 volt version, the LED cycles to RED on the 230 volt versions. The unit's sensitivity to input signals was increased on serial # JSELD 024125 and above; these units may stay ON, even when the input signal is absent. This is a normal condition, and does not compromise the safety, integrity, or dependability of the product in any way. The standby condition that took place on earlier versions was an electronic muting, and both versions draw the same amount of power at all times, whether muted or ON.
