It's complete and helpful manual with good quality of scan. Thanks very much.

The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

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.
2. SAFETY INSTRUCTION
NOTE BEFORE SERVICING THIS CHASSIS READ THE �X-RAY RADIATION PRECAUTIONS�, �SAFETY PRECAUTIONS� AND �PRODUCT SAFETY NOTICE� BELOW. X-RAY RADIATION PRECAUTIONS 1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 25kV(21�) at max beam current. The high voltage must not, under any circumstances, exceed 27kV(21�). Each time a receiver requires servicing, the high volt-age should be checked. It is recommended the reading SAFETY PRECAUTIONS 1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back cover removed involves a shock hazard from the receiver. 1) Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. 2) Always discharge the picture tube to avoid the shock harzard before removing the anode cap. 3) Discharge the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. PRODUCT SAFETY Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are identified by designated symbol on the �PART LIST�. Before replacing any of these components, read the �PARTLIST� in this manual carefully. The use of substitute replacement part which do not have the same safety characteristics as specified in the �PART LIST� may created X-RAY RADIATION. 2. If any FUSE in this TV receiver is blown, replace it will the FUSE specified in the �PART LIST�. 3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor 10mm away from circuit board. 4. Keep wires away from high voltage or high temperature components. 5. This receiver must operate between AC 100-240 volts,50/60Hz. NEVER connect to DC supply or any other power or frequency. of the high voltage recorded as a part of the service recorded as a part of the service records. It is important to use an accurate and reliable high voltage meter. 2. The only source of X-RAY RADIATION in this TV receiver is the picture tube. For continuous RADIATION protection, the replacement tube must be exactly the same type tube as specified in the �PART LIST�.
