MACKIE HR824 26 pages English-only Service Manual contains:
1) HR824 technical overview with the description of front and rear panel switches.
2) HR824 specs
3) Block Diagram
4) Wiring Diagram
5) Packaging management
6) Spare part & final assembly list (for PCB rev A and B) + exploded view
7) Test Procedures (where, how to measure voltage...) including Test Point diagram on the PCB.
8) IC and Transistor charts.
Excellent guide: very clear, good scan quality enabling us to print readable diagram :-)
Note:
Mackie HR824 make extensive use of surface mount devices (SMD). Service on the HR824 must
only be undertaken by experienced service technicians with the right tools, experience and patience to perform surface mount rework when needed.

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.

The service was great and the document was also great. Highly recommend!!!!
If anyone has a users manual... Please email me. need one. $ [email protected]

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.
NOTICES BEFORE REPAIRING
To make the best use of this equipment, make sure to obey the following items when repairing (or mending).
1. Do not damage or melt the tunicate of the leading wire on the AC1 side, including the power supply cord. 2. Do not soil or stain the letters on the spec. inscription plates, notice labels, fuse labels, etc. 3. When repairing the part extracted from the conducted side of the board pattern, fix it firmly with applying bond to the pattern and the part. 4. Restore the following items after repairing. 1) Conditions of soldering of the wires (especially, the distance on the AC1 side). 2) Conditions of wiring, bundling of wires, etc. 3) Types of the wries. 4) Attachment conditions of all types of the insulation. 5. After repairing, always measure the insulation resistance and perform the voltage-withstand test (See Fig-1). 1) The insulation resistance must be 7 to 9.5 M� when applying 500V per second. 2) In the voltage withstand test, apply 3 kV for 1 minute and check that the GO lamp lights. * * * * Breaking current set to 6 mA. Connect the safety checker as shown in Fig-1, then measure the resistance and perform the test. Do not touch the equipment during testing. For details of the safety checker, refer to the supplied Operation manual. Insulation resistance: 7 to 9.5 M� (500 V/s) Voltage-withstand: 3 kV for 1 minute

When servicing and checking on the TV, note the followings.
1. Keep the notices. As for the places which need special attentions, they are indicated with labels or seals on the cabinet, chassis and parts. Make sure to keep the indications and notices in the operation manual. 2. Avoid an electric shock. There is a high voltage part inside. Avoid an electric shock while the electric current is flowing. 3. Use the designated parts. The parts in this equipment have the specific characteristics of incombustibility and withstand voltage for safety. Therefore, use a part which has the same character as the replaced part. Especially as to the important parts for safety which is indicated in the circuit diagram or the table of parts with a ! mark, the designated parts must be used. 4. Put parts and wires in the original position after assembling or wiring. There are parts which use the insulation material such as a tube or tape for safety, or which are assembled so that these parts do not make contact with the printed board. The inside wiring is designed not to get close to the pyrogenic parts and high voltage parts. Therefore, put these parts in the original positions. 5. Take care of the cathode-ray tube. By setting an explosion-proof cathode-ray tube in this equipment, safety is secured against implosion. However, when removing it or servicing from the back, it gives out shock that is dangerous. Take enough care to deal with it. 6. Avoid an X-ray. Safety is secured against an X-ray by giving considerations to the cathode-ray tube and the high voltage peripheral circuit, etc. Therefore, when repairing the high voltage peripheral circuit, use the designated parts and do not change the circuit. Repairing, except indicates, causes rising of high voltage, and the cathode-ray tube emits an X-ray. 7. Perform a safety check after servicing. Confirm that the screws, parts and wiring which were removed in order to service are put in the original positions, or whether there are deteriorated portions around the places serviced.
