<p class="Wp-Body-P"><span class="Body-C-C1">The 2A3 Amp</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">Of all the DHTs (directly heated triodes), the 2A3 tube sits at the pinnacle. Introduced
in the 1930s, the 2A3 has continued unchanged to this day. Some new production tubes
are available, but most manufacturers continue to use new old stock. RCA was a prolific
maker of this tube. </span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">Tubes, especially directly heated triodes, have the lowest distortion signature of
any amplifying device. Used in simple circuits, the 2A3 tube gives great clarity
in music. Its portrayal of musical tone, texture, and harmonics is superb. In a well
designed amp, the 2A3 brings music alive.</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">Lyrita‘s 2A3 amps are single-<wbr>ended designs, as originally intended for this tube.
SET-<wbr> single ended triode. The circuits are simple, and use transformers extensively.
Amp configurations can be customized for the user.</span></p>

<p class="Wp-Body-P"><span class="Body-C-C1">The GM70 Amp</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">To provide a substantial increase in power output, and maintain the signature of
the single-<wbr>ended tube amp, the GM70 tube is ideal. Its properties are very similar
to the renowned 845 tube -<wbr> though the construction, pin layout, and heater requirements
are different. The GM70 is a more robust and reliable tube. </span></p>

<p class="Wp-Body-P"><span class="Body-C-C1">DHT Line preamp</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">This line level preamp uses the Russian 4P1L, as a directly heated triode, in a very
simple design. Filament bias is used, which aids in simplicity and stability. An
audio transformer serves as a load to the tube, as well as isolates the output. This
also controls microphonics in the tube. Volume control is on the output. </span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">The sound is rich in tone, with excellent dynamics. A great start to the amplification
chain.</span></p>
<p class="Wp-Body-P"><span class="Body-C-C4"> Tubes 4P1L, 6C5S</span></p>

<p class="Wp-Body-P"><span class="Body-C-C1">Phono preamp</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">Tubes handle low level signals beautifully, with unmatched linearity. They are ideal
for the minute signals from the phono cartridge, to amplify and equalize to RIAA
specifications.</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">A new circuit design uses the high transconductance, high gain, dual tube, the Russian
6F12P. This tube brings great clarity in music, with excellent micro and macro dynamics.</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">The active circuit has enough gain for MM (moving magnet) and high output MC (moving
coil) cartridges. </span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">For low output MC cartridges, a step-<wbr>up transformer is required, ahead of the active
circuit. Consider this as part of the cost of a low output MC. Lyrita recommends
step-<wbr>up transformers from CineMag.</span></p>
<p class="Wp-Body-P"><span class="Body-C-C2">Our environment is becoming more noisy electrically, with high levels of RFI (radio
frequency interference). The high gain tubes used in phono circuits are very susceptible
to RFI pickup. The only way to prevent this is to provide shielding to the entire
circuit and tubes. So, the chassis becomes a steel black box.</span></p>
