12/16/2023 0 Comments Old transistor radio green![]() ![]() Ray Charles, Bobby Vee, Don Gibson, The Shadows, Del Shannon, Johnny Tillotson, Brenda Lee, Carol King, on and on. All the great British and even more US acts on there. ![]() Unmissable was the Top 20 on Sunday nights 11pm to midnight - great before next day at school. I heard the Beatles live on his show before they were really famous - wondered what all the screaming in the studio was about. Serials like Dan Dare "pilot of the future" and Dick Barton (special agent) were on there, too, in the 1950s IIRC.Įach half hour program tended to be the records from a particular label (DECCA, Parlophone, etc.) hosted by DJs well known in the UK - including Jimmy Saville. Luxembourg was on "208 metres medium wave" - started about 7pm with some religious program - kindof like American evangelism? - then pop music in half-hour chunks from 7.30 pm on till midnight (possibly later). heaven! One station based itself on one of the WW2 anti-aircraft towers built in the Thames estuary, IIRC. The BBC was hidebound by regulation and the musicians' unions, so they hardly played recorded pop stuff until forced to by the advent of the offshore pirate radio stations who played it wall to wall from about 1965. Radio Luxembourg was the hottest pop radio station in the 1950s and 1st half of 1960s in the UK when I was growing up. you wouldn't be caught listening to Western propaganda in Communist countries? *?confused* What gives? Why bother making a key dedicated to one particular radio station? Was it really that good to warrant its own button? Was tuning to it so hard that a very precise local oscillator was required? Or was there really a need -as suggested by some people- to be able to quickly switch it off/change station so that e.g. And, in fact, my Telefunken Bajazzo Compact 3000 does have a large oscillator crystal inside it. ![]() Some googling in German sites, the only ones which seemed to have a shred of information on the topic, resulted in mentions of a "grüne Luxemburg-Taste" (green Luxembourg key), present in many old German-made radios of the 60s and 70s, which presumably used a local crystal oscillator at 6090 kHz to tune to a particular SW station in the 49 m (Radio Luxembourg, precisely). I thought it would turn the backlight on/off (lux = light) but instead it turned the radio on in a weird mode, which sounded like shortwave static most of the time, but the tuning knob was inactive in this mode, and pressing the AFC button set the radio in aux-in mode (on that radio, aux-in was activated by selecting the KW (SW) band and AFC together, so presumably the radio tuned to a particular SW frequency with the green lux. Secondly, the actuation of the eye might not work due to a bad 1 meg resistor usually hidden inside the eye tube socket across pins 2 and 4.I have recently restored a Telefunken Bajazzo Compact 3000 "boombox" (if it might be called that, given the design and the era), and was puzzled by the purpose of the green "Lux." button on it *scratchchin* There is no way to rejuvenate these eye tubes but you can make a dim one brighter by slightly increasing the filament voltage if possible. First, dim image which is a function of how many hours the tubes been on. There are two common issues with the operation of these. The 6T5 has just a little pin in the center and it operates liike a camera iris. These all have the silver button in the center of the eye and show a pie shaped image when operating. There is a 12V filament version with and octal base ( the 1629 type) which was often used in test gear, its cheaper and so there are adapters to use it in place of the others. ![]() Not really, the images on the 6E5/ 6G5 / 6U5 all match but the 6E5 is the most sensitive. Is there a way to tell them apart visually? I have a GM branded 6?5 tube here that I tested as a 6E5, guessing about it. ![]()
