Tube Preamplifier SR-21T3 SE












FEATURES


Extensive point-to-point handwiring, fully hand-made preamplifier tube,
allocated preamplifier for audiophile–of enthusiasts of tube technology.
The preamplifier carried out is on four tubes 6922, the attractive design provides very good sound that you can enjoy the music for a longer time and being touched.

· Automatic biasing circuit, zero feedback designs.
· Power supply and audio section are heavily shielded.
· The circuits are arranged to achieve the shortest possible signal path and to obviate internal wire  connections from the input to the output terminals.
· Tube complement: 4* 6922 dual triodes, 1 * 6CA4 with double chokes rectifier.
   Four  6922 tubes work under four independent voltage regulators.
· Using DACT CT-2 high precision Attenuator 
· Three set of independent Transformers for the power supply
