Early on I mentioned additional parts I used in a more advanced kit than the standard HV Kit for this the Solenoid Driver board. This kit is not mandatory, but I find that on most of these boards, if the Transistors are faulty, something before or after are also out of tolerance or faulty.
Here's the list ;
R35 - Resistor 100K 1 Watt
R51 - Resistor 22K 1/2 Watt
R52 - Resistor 390 Ohm 1/4 Watt
R54 - Resistor 8.2K 1/4 Watt
R55 - Resistor 1.2K 1/4 Watt
R56 - Resistor 82K 1/2 Watt
VR1 - Zener Diode 140V 2 Watt
CR21 - Diode 1N4004
C27 & C28 - Capacitor 0.1uF 400V Polyester
Most of these parts SHOULD be available locally, but I bought them from Great Plains Electronics in the States.
Here's a pic of the advanced kit ;
Q22 & Q23These two transistors have some spacers which need to be retained and used with the new transistors in the HV Kit. Do not discard them. They look like this ;
Next step - Install the parts and replace the connectors.
