MORE THAN 100 UNITS SOLD IN EBAY

I've repaired many Mackie power supplies from mixers (Onyx Universal Supply) for a local radio station. They will eventually fail. Experience demonstrated that beside repairing the fault, you can prevent future interventions by replacing some capacitors. This KIT contains all you will ever need to put it back to work for a long time in 90% of the possible failures (blinking power, buzzing, no power at all, voltages missing, etc.)

This KIT is suitable for Onyx 1640, 1620, 1220, 800R, DS3232 and d.4

The schematics included is for all these versions.

Even experienced technicians will have a hard time diagnosing this power supply, so beside the schematics, I will provide a flow chart to help you detect the problem. This is not for beginners, but you can take this kit to your local repair shop and they will gladly do it for you - most of the times, sourcing the components takes a huge amount of time, part of them are really hard to find and buying them individually is really expensive. All the provided components are good quality and tested before shipping.

This is what you get:

2 Fuses T2.5A (just in case)
1 Rectifier bridge 8A 600V
13 470µF 25V capacitors (105º)
1 3300µF 10V capacitor (105º)
2 47µF 25V capacitor (105º)
1 4,7µF 63V capacitor (105º) - new addition, not pictured yet. Now all electrolytic caps can be replaced
1 TOP249Y switched power supply IC (U1)
1 LM317 regulator IC (U2)
1 diode UF5407 3A 800V (D13)
1 diode SR860
1 SMD optical coupler MOC8102 (U3)
2 zener diodes P6KE100A 100V 5W (D12, D18)
2 SMD diode 1N4148W
2 SMD diodes S1G
1 resistor 36KΩ 3W (R37)
1 fuse resistor 10Ω 1/4W (R42)
1 NTC thermistor 10Ω 6A (R36)
