6c33cb is an electronic tube originating from USSR or today’s Russia. Initially it was invented by the Russian Army and it was kept as a tightly guarded army secret. In 1976 certain Russian pilot navigating famous Russian MIG – 25 Jet Plane deserted Russian Army by landing this plane on Japanese soil. As the MIG – 25 plane was the latest technological invention of that time evidently Japanese engineers made an assessment and to their surprise in the plane found electronic tubes. Russian MIG engineers worked to small details. Silicium dissolves from the impact of atomic bomb but the tubes continue functioning. Japanese audiophiles were excited by the discovery of the electric tubes and soon they gained popularity in production of OTL amplifiers. In this way wider market became available and Russia had started exporting them through out the World.
Frame is hand made from oak-wood, rest from messing. I did not make an attempt to weigh it, certainly it is not an object that can be lifted and moved around at one’s ease? Will try not to glorify the sound it produces better come over for a snoop!
In SE type of amplifiers the main trouble is the small power meaning that speakers of higher sensitivity are a must. In case of 6c33cb amplifiers there is no need for sensitive speakers as the amplifiers has more than enough power to generate sounds of the highest quality.
