SA Lab Samson is tube amplifying trio consisting of preamplifier and two monoblocks.
Samson has become the very first SA Lab amplifier with output tubes working in ultra linear mode. 120 W (4 Ohm) push-pull monoblock’s output stages were built on four beam-power tetrode 6п36с (USSR, 1978). Furthermore there are ECC82 (Tungsram, 1970) and driver 6п6 (USSR, 1968; can be replaced to 6v6). All the bulbs are of highest quality and conditions.
Head of SA Lab designed the very complicated output transformer that takes a lot of time for manufacturing exclusively by hands. Transformer’s special auxiliary winding bears interfering signal that is mixed into output signal under very limited negative feedback of 3 dB. The result is very low distortions within the whole audio spectrum.
