VLF1 PARTS LIST
Sort and “check off” the components in the boxes provided. We do our best
to pack all our kits correctly but it is possible that a boo-boo has occurred
and we missed a part. Please note that physical descriptions of parts are for
those currently being shipped. Sometimes the parts in your kit may have a
different appearance but still have the same values.
 3 10K ohm resistor [brown-black-orange] (R1,R2,R3)
 2 1K ohm resistor [brown-black-red] (R6,R10)
 2 270 ohm resistor [red-violet-brown] (R5,R9)
 1 18 ohm resistor [brown-gray-black] (R8)
 1 1M ohm resistor [brown-black-green] (R4)
 1 3.3K ohm resistor [orange-orange-red] (R7)
CAPACITORS
 5 .1 uF ceramic disc capacitors [little green, marked 104] (C6, C7,
C11, C12, C14)
 2 .015 .uF polyester film [brown, marked 153] (C2, C3)
 2 .0082 uF Mylar or ceramic disk capacitors [steely blue rectangles, or
marked 822] (C1, C4)
 1 40 pf adjustable cap [little cube with phillips indent on top] (C10)
 2 22 pf ceramic disc [marked 22] (C8, C9)
 2 10 uF electrolytic (C5, C16)
 1 1 uF electrolytic (C13)
 1 1000 uF electrolytic [big whopper cap] (C15)
INDUCTORS
Note: Inductor color codes can be hard to read. If you don’t have an LCR
meter, get a bright light and a magnifying glass. You can also check with an
ohmmeter to make sure that what you think is an inductor is not a resistor in
disguise. The inductors in this kit have almost zero resistance.
 2 22 uH [look like turquoise or tan resistors, red-red-black] (L1, L3)
 1 100 uH [brown-black-brown] (L4)
 1 27 uH [red-purple-black] (L2)
SEMICONDUCTORS
Note: Chips may have different numbers and letters on them; the important
thing is that the numbers listed in brackets are there
 1 MC74HC04AN [7404] Hex Inverter (U2)
 1 CD74HC4053E [4053] CMOS analog Multiplexer/Demultiplexer (U1)
 1 2N3904 NPN bipolar transistor (Q1)
 1 7805 5 volt regulator (VR1)
