Excellent, fast delivery, excellent product. Good luck!

This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955

For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.

Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe

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.

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.
