WPC High Voltage rebuild kit A-20516

24 piece electronic components rebuild kit for the High Voltage section of Williams A-20516 WPC system A/V controller boards.

This critical update kit is designed to prevent burnt circuit board damage from original components. Take a moment to inspect the rear side of the A-20516 controller board and you will see a blackened area under the high voltage circuit area.

Installation requires circuit board soldering skills and about 20 minutes.

Kit includes:

• 1N4759A zener diode (1 piece) D2
• 1N4758A zener diode (2 pieces) D1, D18
• 1N4742A zener diode (2 pieces) D3, D5
• 1N4004 diode (1 piece) D4
• 2N5551 (MPSD02) transistor (2 pieces) Q2, Q3
• 2N5401 (MPSD52) transistor (2 pieces) Q4, Q5
• MJE15030 transistor (2 pieces) Q1,Q7
• MJE15031 transistor (1 pieces) Q6
• 120 ohm 1/2 watt resistor (2 pieces) R30, R31
• 47K ohm 1/2 watt resistor (4 pieces) R25, R26, R27, R29
• 56 ohm 1/4 watt resistor (1 piece) R24
• 4.7K ohm 5 watt radial resistor (1 piece) R43
• 1.8 Kohm 5 watt radial resistor (1 piece) R44
