I was having a hard time finding the problem with this Mackie 1604 unit. I didn't have a schematic. Went looking on the web and found your site and the price was more then reasonable. Ordered it and within the hour had the manual and within 15 minutes had the unit fixed. Best $4.99 I ever spent. Thank you.

This is a service manual in every sense of the word ( French and German versions of the text are included, as well as English..)
There are explanations of the mechanical and electrical functions, plenty of mechanical drawings, and the needed schematics. The quality of the scanning is excellent - all the component values are clearly legible - and very usefully there are pcb component layouts, so you can find a component on the schematic, and then very quicky pinpoint its physical location on the relevant pcb.
I cannot see how I can give this manual any less than the maximum 5 stars! Great value for money, which will pay for itself immediately. Excellent all round!

ADJUSTMENT
1. IC10 (TDA7513) -The Tuner adjustment method
� When IC10 and its circumference are fixed, according to the following order, it readjusts if needed. � The adjustment item changes with parts to exchange. Please refer to "Parts vs Adjustment item table". 1-1. VCO Coil Adjustment -- Adjustment of Tunning Voltage Voltage Check Point : Vt-Check Land (PWB Side_B, around D506) Adjustment Coil : L507 (VCO Coil) The adjustment method : VCO coil is turned and adjusted according to the following tables.
TYPE E/M K J W(Wide Band) Mode AM AM FM FM freq. 1611kHz 1700kHz 90.0MHz 108.0MHz Voltage 5.5 ± 0.1(V) 5.8 ± 0.1(V) 5.6 ± 0.1(V) 7.2 ± 0.1(V) Fig (C) (C) (C) (C)
1-3. Adjustment of FM_ANT&RF Coil Voltage Check Point : S_METER-Check Land (PWB Side_B, around W572) Adjustment Coil : ANT_Coil = L505 RF_Coil = L506 Setting of Signal Generator : Refer to the following tables.
TYPE E/M K J W(Wide Band) MODE FM FM FM FM freq. 87.5MHz 87.9MHz 76.0MHz 65.0MHz Mod. OFF OFF OFF OFF ANT Input 5 or 11dBuEMF 5 or 11dBuEMF 5 or 11dBuEMF 5 or 11dBuEMF Fig (A),(C) (A),(C) (A),(C) (A),(C)
xThe appearance and the coil with which S-METER DC voltage serves as the maximum are turned and adjusted in the above-mentioned SG input. �By the above-mentioned adjustment method, same adjustment is performed to both sides (ANT&RF Coil). 1-4. Adjustment of STEREO (adjustment of 456k-VCO) Adjust in TEST_MODE � How to enter the test mode While pressing on [ FM ] and [ PRESET 6 ] keys, reset the unit. � Adjustment method Complete on condition that show "ALL OFF" when pressing on [ PRESET 1 ] and [ PRESET 6 ] keys. (Writing adjustment valve to the EEPROM.) Effect of adjustment is in cofirmation of adjustment status at [ PRESET 4 ] key. � Display of [ PRESET 4 ] Adjustment "OK" : 14seg model "E2P OK" 7seg model "EPO" Adjustment "NG" : 14seg model "E2P ERR" 7seg model "EPE" � Releasing the test mode Reset mode only. ACC off, Power off, Power down and Remove the panel mode is not releasing.
M : AM Adjustment For Your Information : The frequency of SET is only set up by Pre-Set-Key in case this adjustment 1-2. Adjustment of 1st & 2nd-MIX Coil Voltage Check Point : S_METER-Check Land (PWB Side_B, around W572) Adjustment Coil : 1stIFT = L508 / 2ndIFT = L509 Setting of Signal Generator : Refer to the following tables
TYPE K E,M,J,W MODE AM AM freq. 1000kHz 999kHz Mod. OFF OFF ANT Input 35dBuEMF 35dBuEMF Fig (B),(C) (B),(C)
xThe appearance and the coil with which S-METER DC voltage serves as the maximum are turned and adjusted in the above-mentioned SG input. �By the above-mentioned adjustment method, same adjustment is performed to both sides (1st&2nd MIX Coil).
