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.

I've generally sourced electronic parts cheaply at http://www.futurlec.com.au; they actually come from OS (Malaysia or Indonesia or ?) but the pricing is good and the postage is reasonable as well, and they don't mind hobbyist orders.
