Radio engineering time travel (to 1921)

I invite you to look at the "pictures" related to radio technology. They come from various sources. The gallery has its sister version in Polish and Russian. Versions in other languages will be added successively. More detailed descriptions can be found in other language versions (articles are related and can be displayed by clicking on the icons with flags on the left, top of the TRIODA website). Of course, I will complement translations of signatures quite slowly. All descriptions are displayed using the present tense and not the past - this is not a mistake only deliberate action - a reference to the original descriptions from those years. In order not to delay the possibility of viewing the gallery, this site is made available as a "site under construction" - for which I apologize to all guests. At the beginning and end of each set of photographs there are links allowing to change the period - calendar year.

Na pierwszy rzut oka jeszcze jeden stereofoniczny wzmacniacz lampowy w układzie przeciwsobnym. Klasyczny wygląd z trzema puszkami zawierającymi transformator sieciowy i dwa transformnatory głośnikowe oraz pięknie wyeksponowaną "baterią" lamp elektronowych. Producent zaprezentował nam również zestaw kondensatorów elektrolitycznych - to może nieco rzadziej spotykane, ale również niezbyt odkrywcze podejście projektowe. Podsumowując - wzmacniacz ładny, ale wieje nudą. Ostatni rzut oka na zastosowane lampy i nagle niespodzianka - obsada lamp dziwna, że nie powiem zwariowana. I to tutaj właśnie kryje się tajemnica tej konstrukcji. Ale zacznijmy od początku...

With a little help of Allegro (online auction site) I became the owner of the 100BIS PS1 tube device. Although I bought it outside the auction but Allegro was unwittingly involved in the transaction. The manufacturer of the device apparently did not attach importance to such a "trifle" as the device name. According to the inscription on the front panel and content of the Instruction Manual I bought a "control panel", and according to the rating plate information and leaflet I bought a "control console". So let me use the following description of the term -"tube mixer".
