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.

After the PS-1 control unit, I became the proud owner of 100Bis tube amplifier. This amplifier and PS-1 control unit constitute  an electroacoustic set. More specifically, the set includes two such amplifiers and one control unit. Amplifier, which is presented below is of excellent condition. The only apparent damage (except for scratches resulting mainly from improper storage) is a small loss of the plastic shield, which acts as an amplifier decorative front panel.

The QUAD II tube amplifier was manufactured by a company with big traditions, as founded by Peter J. Walker in 1936, SP Fidelity Sound Systems, renamed later in the same year to the Acoustical Manufacturing Co. Ltd. The company was initially located in London, but after a bombing in 1941, was moved to Huntington. The name "Ouad" is an acronym for "Quality Unit Amplifier Domestic" and I must admit that the equipment bearing this name deserve to be called a high-quality audio equipment. The name "QUAD", used for many years only to manufactured products became so known in the market that in 1983 the company changed its name to QUAD Electroacoustics Ltd.

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".
