			<description><![CDATA[<b><i>Cementimental says:</i></b><p>it&#039;s good practice to be consistant with the direction of your resistors on the board simply because it looks neater and is easier to read their colour codes if you need to troubleshoot</p>]]></description>

These 2 resistors in parallel have an equivalent resistance of ~45K.</p><div class="quotebox"><cite>Peter Dodge wrote:</cite><blockquote><p>R3 is 4 100Ks with a 62K or something like that with some heat shrink tubing on it.</p></blockquote></div><p>Same issue as R5 above - parallel resistors do not sum together. 4 * 100K + 62K in parallel would give ~17.8K.</p>]]></description>

An 82k in parallel with an 100k will equal 45k. They need to be in series to get 182k. R3 is going to be way way lower with 5 resistors in the mix.</p>]]></description>

			<description><![CDATA[<b><i>rebb says:</i></b><p>Resistors do not have polarity, so does not matter. For troubleshooting, have you measured that your opamp gets valid voltage? <br />You can also check all the connections with continuity test on multimeter. Also add pic of the bottom side of your build.</p>]]></description>
