The new S.E.X. amp
The amplifier's power output is approximately 2 watts RMS per channel at 10% THD at 500Hz, similar to a single ended 45 tube amplifier.
Frequency response at 1V output is -3dB at 27Hz and 22kHz. The amplifier has an input sensitivity of .62V RMS and a gain of approximately 15 dB at 1 kHz and can be wired for 8 ohm or 4 ohm speakers. 16 ohm speakers will run well on the 8 ohm tap at slightly reduced power levels. Input impedance is 100Kohms.
Assembly is a one or two evening affair, designed for the builder with little or no kit assembly experience. A very thorough assembly manual (the S.E.X. Manual) is included in Adobe PDF format on a CD ROM, containing step by step printed instructions you check off as you work, detailed photos of the chassis underside and components, and a thorough
checkout procedure.The combination of low noise and ample transformer coupled output drive means the S.E.X. amp is perfect for use both as a loudspeaker amp and as a headphone amp, It works great with high efficiency (97 dB or higher) speakers for listening room systems that work well with similarly powered 45 amps, and practically begs to be plugged into computer sound cards and smaller speakers for desktop audio systems. An IHF standard output configuration on the headphone jack means exceptional low noise performance with headphones of virtually any impedance. The integral level control makes a very simple system possible. Only the addition of a source (CD player, portable disc player, Ipod, sound card, phono preamp, tuner, etc.) and speakers or headphones is needed to get the three dimensional, highly resolved sound of single ended triodes.
