complete part-lists and pcb layout, schematic diagram is good enlargable,
 ;
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.

Service bulletin # 9604 rev1 - October 1998 To: All harman/kardon Service Centers Models: FL8300 Subject: Digital Output Level
Service Bulletin
This is considered a Minor Repair
The Digital Interface Standard recommends D/A converters have a minimum Input sensitivity of 200 mV. In early FL8300 production units, the Digital Output level was 240 mV ±10% peak to peak. Based on our research, we found that some D/A converters require more than 240 mV for intermittent free operation. In the event you receive a FL8300 from a consumer with the a complaint �Intermittent Sound from External D/A converter�, check the serial number in the table below. If the FL8300 has a serial number higher than indicated in the table below, connect a properly working D/A converter to the Digital Output and verify interruption free operation. Also confirm the Digital Output level of the FL8300 is 500 mV ±10% Peak to Peak. If the FL8300 passes these two tests, advise the customer to have their external D/A converter and connecting cables checked. If the FL8300 has a serial number lower than indicated in the table below, perform the following modification: 1) With the unit plugged in and turned on, push the �open/close� button to extend the drawer fully; then turn the unit off and unplug it. 2) Open the top cover (6 screws). 3) Remove output board PCB3 from the rear panel (4 screws). This board can be pulled back and modified without completely removing it from the chassis. 4) Locate resistor R901, it may be a 680 ohm resistor or a jumper wire; replace in either case with a 0.47 uf capacitor h/k part# 5354-474593. 5) Locate R903 and change from 680W to a 4.7kW resistor - h/k part # 3029472970. Re-attach output PCB3 to the unit. 6) Connect a 75 Ohms cable to the digital output jack. Terminate this cable with a 75 Ohm load; connect an oscilloscope to the 75 Ohm termination resistor. While playing a CD, confirm the output of the signal is now 500 mV ±10% peak to peak. 7) Reassemble the FL8300 and test all functions.
Model FL8300 Serial number 120V IN0019-01001 to IN0019-19393 FL8300 IN0019-19394 Serial number 230V IN0020-01001 to IN0020-04500 IN0020-04501 Status May have low digital output for some applications Factory Installed * Action Replace R901 with 0.47 uf mylar capacitor h/k part# 5354-474593 Replace R903 with 4.7k ohm resistor h/k part# 3029472970 NONE REQUIRED
* Factory modification of the FL8300 starting with the serial numbers indicated in the above table consisted of:
R236: 1k Ohm R901: Jumper or 680 Ohm R903: Changed from 680 Ohm to 4.7k Ohm. Digital output level into 75 Ohms: 500 mV ±10% peak to peak.
