Radio engineering time travel (1930)

I invite you to look at the "pictures" related to radio technology in 1930. 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.

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".

Piotr Mason (HAIKU-AUDIO)

Tube amplifier named "Auris" was produced by Audio-Akustyka. According to the specification, it can work as a pentode or triode amplifier, in Push-pull or Single-ended mode, with or without a negative feedback, and in the mysterious "turbo" mode. The manufacturer does not allow peering into the housing due to the use of many "non-standard proprietary solutions". Time to break the seals and keep one's ear to the ground.

Under the name of A. R. Electronics hides Audio Electronics Company - a small workshop producing tube amplifiers in Gdańsk. For the first time I saw a product of this company at the end of the 90-ies of the last century, when I became the happy owner of the amplifier with the symbol SE-41. Unfortunately, I do not know if the company still exists, because for some time I have no information about new A.R. Electronics amplifiers. Anyway, in the secondary market one can meet the A.R. Electronics amplifiers characterized by good sonic parameters and interesting design line. Despite the lack of information in the official offer, A.R. Electronics produce or produced not only amplifiers but also other audio equipment such as tube preamplifiers. They were made to individual order or in a small number of units. To this type of products belongs a tube preamplifier with the symbol PL-02.
