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.

      "Transistor low-frequency amplifiers have contributed to the emergence of a new type of distortion called transient intermodulation distortion (TIM). This type of distortion can occur in an amplifier with very small static nonlinear and intermodulation distortions. It is undetectable with ordinary with the help of a sinusoidal sonar. Meanwhile, the human ear is very sensitive to dynamic distortions, which occur especially during loud and high tones in the reproduced sound, giving the impression of metallic and disturbing sound ...

  The PCL86 tube belongs to the so-called "television tubes", i.e. tubes used in TV sets produced as the last models of tube televisions. In principle, the models produced at the end of the 70s and the beginning of the 80s of the last century are already transistor-tube constructions. A classic example of such a TV was "Libra" produced at the Warsaw Television Plant (WZT). I associate with this construction sentimental memories, because I belonged to the group of so-called "composers" who, as the name suggests, dealt with assembling these televisions from parts obtained from "Bomis" (younger Internet users need to search the web a bit to find out what it was).

  Libra TV sets were owned by my neighbors and close family members. They were satisfied with the use of deficit devices at that time, and I had a nice financial source to support my modest student budget. With some embarrassment, I must admit that the television tubes used in "Libra" TVs were a necessary evil for me at that time. I had to accept this being dependent on the ideas of the designers of the WZT. Like other television set makers, I immediately gave them up as soon as full-transistor televisions appeared, such as Vela, Telefunken etc.
