The CS-300F model is equipped with GE JAN 6197 valves, developed for use in computers. We are the first in the audio world to use this valve.
The 6197 valve produced by General Electric (USA) is a valve of particularly high quality that complies with the North American military standard JAN (Joint Army and Navy).
This valve is produced with special quality control from the beginning on an independent production line, separate from consumer valves and is intended for military supply.
We purchased these tubes several years ago and have since been searching for the best circuit design to get the most performance out of them.
For the circuit of drivers We have used the 17EW8 valve, produced for the world of hi-fi by the largest Japanese electronics manufacturer.
– Generous use of components of the highest quality
– WBT type connection terminals
– Circuit with self-adjusting bias that accepts new valves without having to adjust the bias and that can adapt to the consumption of the valves or to the inequality between them
– Side panels made of natural Canadian white ash wood. This wood is very hard and heavy and is generally used to make baseball bats and bass boat oars.
