Clarinet Audio Design LINE Stereo Preamplifier

The Clarinet's LINE is a two stages, line level input, stereo preamplifier is designed with a 12AY7/6072 tube. The LINE's gain (23dB) is matched with our PHONO amplifier but it works perfectly with any other line level output source (CD player, Tuner, etc.) also.

The device is fully hardwired - signal and PSU section - with a special silver-wire and uses in-house constructed silver lead out wires resistors on tagboard with silver capacitors and in-house made transformers.


For the best sound the preamp contains an input-selector switch with solid silver contacts and in-house constructed stepped volume control. The input and output connectors are of the highest-grade pure silver. 

The case of the device  is made of aluminium alloy.
