Parts Checklist for BYOC  Parametric EQ Kit

Resistors:

These are 1/8th watt resistors.  They are very small.  You may need a

magnifying glass.  If you still have trouble reading the color bands, we suggest using a

multi-meter to identify the value of each resistor

4 - 331/330ohm (orange/orange/black/black/brown)

15 - 162/1.6k (brown/blue/black/brown/brown) or 1.62k (brown/blue/red/brown/brown)

24 - 512/5.1k (green/brown/black/brown/brown) or 5.11k

(green/brown/brown/brown/brown)

4 - 104/100k (brown/black/black/orange/brown)

2 - 474/470k (yellow/purple/black/orange/brown)

Capacitors

2 - 2n7 or .0027µ film (272)

2 - 12n or .012µ film (123)

6 - 100n or .1µ film (104or µ1)

9 - 10µf aluminum electrolytic
