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.
. I am a fan of Lotus team, so it's no surprise that I like this color combination. The only problem is the inability to take a picture in a way that surrounding objects are not reflected in the golden housing. It is presumed that one of the purposes underlying the company was to promote electron tubes produced by them (the preamplifier has as many as 8 tubes). This has been only partially successfull. Preamplifier certainly served the brand, but rather as an independent audio device, than the device equipped with tubes with JJ logo. In some copies, which I inspected I found tubes from other manufacturers.
