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.

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 :)

<TAPE PLAYER> 1. Azimuth Adjustment Settings : � Test tape : � Test point : TTA-320 PHONES JACK (J102) 2) Set the tape speed (using speed adjustment SFR). 3) Restrict the motor rotation by hand (or turn PAUSE ON). 4) Remove your hand and listen to the beginning of the tape-run. 5) When the rise of tape running is smooth, no more adjustment is necessary. If wow continues for 1 to 2 seconds at the rise time, Reduce the combined resistance according to procedure 6 and check that the tape starts running smooth. 6) Solder the resistor pattern according to the table below. 2.

� Adjustment location : Azimuth adjustment screw � VOLUME : � GEQ : MAX NORMAL
Method : Play back the 8kHz signal of the test tape and adjust so that the output becomes maximum.
(J102) � Adjustment location : SFR101 � GEQ : NORMAL Method : Play back the test tape and adjust for 3015Hz ± 10Hz. 3. Motor Load Adjustment Perform the STOP to PLAY after the motor is replaced. When the tape starts running smooth, this adjustment is not necessary. this adjustment following the procedure below. 1) Solder only medium resistor pattern (B) of the MOTOR AND GOVERNOR MATCHING ADJ. Resistor group.
7) Finally recheck the tape speed. Caution : Cool the patterns down to normal temperature after soldering. If the pattern remains heated, the governor circuit does not operate normally.
