PAiA 9407k Tube Preamp
The 9407k preamp is a combination of tube and solid-state circuitry. A NE5532 opamp drives two 12AX7 gain stages, which are fed low plate voltages ("starved plate") to exaggerate their inherent non-linearity. The amount of tube saturation may be adjusted by a "blend" knob which blends between the pre- and post-tube stage signal. <p style="text-align: center;"><img class="size-full wp-image-640 aligncenter" title="©PAiA Corp." src="http://wiki.diyrecordingequipment.com/wp-content/uploads/2010/09/tmp.jpg" alt="" width="552" height="53" /></p> <strong>Notable Features:</strong> <ul> <li>"Starved plate" circuitry</li> <li>Uses two Sovtek 12AX7 tubes</li> <li>Adjustable "Tube Drive"</li> <li>Includes wall-mount power supply</li> <li>Designed for PAiA's 9407C case</li> </ul> <strong>Price: </strong>$82.31 <strong>Adjusted Cost: </strong>$96.54/channel (two channels) <p style="padding-left: 30px;">PAiA gives a $12 discount for two kits, making the price $152.62.
