For a long time I planned to make an amplifier on the famous "little devil" - the 6S33S tube. I have heard many contradictory opinions about this tube. The main disadvantage is the instability of its parameters over time. Changing the value of the anode current during the work of an unheated vacuum tube is a constant topic of almost every discussion forum dedicated to vacuum tubes. With all its chimericity, this vacuum tube mysteriously attracts designers. Why? I do not know. Probably everyone who did something on it had their own reasons. As for me, there are several reasons. I will mention one - this tube looks great, and these three devilish horns - great !!!
Some time ago I heard from a friend that his friend saw in the living room of his friend a simple amplifier on a 6S33S tube. Apparently it sounded great. This friend of mine decided to make himself the same amplifier and for this purpose acquired the schematic of the amplifier circuit. The schematic diagram lasted two years, until it fell into my hands. There are no revelations in the amplifier's system design. There are many such schemes on the Internet. However, this is not a disadvantage for someone who would like to build an amplifier according to a proven electronic system.
Slightly under the pressure of a friend already mentioned twice, I decided to listen to the amplifier on the 6S33S tube in person. It took me some time to gather the necessary elements, but finally I started to work.
