The list of my radio & TV collection!

The story of how the era of lamp technology smoothly turned into the era of transistor radio ... Icon_rolleyes


Quote:
Transistor all-wave radio Akkord Pinguin U60 .1960 year. Another model of the very popular German company Akkord Radio is Pinguin U 60. This is the first fully transistor all-wave radio receiver of the company, which almost does not differ in design from the tube U59 of the previous model year. For comparison - the model is 59 years old, find 10 differences)). The back covers are also completely identical. The only difference is the presence on the old lamp model U59 of three screw holes on the top of the case for better cooling of the radio tubes ... But under the cover everything is much more interesting - everything is the other way around here, the only similarity is the metal chassis, the same KPE design, range switch and intermediate circuit amplifier screens. It seems that the radio tubes here were simply mechanically replaced with transistors, of which there are only 8 pieces. Interestingly, in addition to the FM block and range switch boards, the installation of intermediate and low-frequency amplifier elements is mounted - they are located on the back of the chassis and therefore the visible side of the chassis looks almost empty ... unlike the lamp predecessor. )
The facade of the case is also almost identical to the previous model, the only difference is the availability of space for the Transistor nameplate (unfortunately lost ....), the sequence and placement of the range switch keys and the scale graph. The same 4th frequency range within the same frequency range. The “transistor" is slightly lighter than the tube ancestor, although it’s only less than a kilogram - 3.1 kg instead of 4.
Next in line are comparative tests with lamp ancestors. )))

Транзисторный всеволновой радиоприемник Akkord Pinguin U60 .1960 год. Еще одна модель очень популярной немецкой фирмы Akkord Radio - Pinguin U 60. Это первый полностью транзисторный всеволновый радиоприемник фирмы, который дизайном почти не отличается от лампового U59 предыдущего модельного года. Для сравнения - модель 59 года, найдите 10 отличий )). Задние крышки также полностью идентичны. Единственное отличие - наличие на старой ламповой модели U59 трех винтиляцийних отверстий на верхней части корпуса для лучшего охлаждения радиоламп ... А вот под крышкой все гораздо интереснее - здесь все наоборот, единственное сходство это металлическое шасси, такие же по конструкции КПЕ, переключатель диапазонов и экраны контуров усилителя промежуточной частоты. Такое впечатление, что радиолампы здесь просто механически заменили на транзисторы, которых здесь всего 8 штук. Интересно, что кроме ФМ блока и плат переключателя диапазона, монтаж элементов усилителей промежуточной и низкой частоты является навесным, - они размещены на обратной стороне шасси и поэтому видимая сторона шасси выглядит почти пустой ... в отличие от лампового предшественника. )
Фасад корпуса также почти идентичен предыдущей модели, - разница только в наличии места под шильд «Транзистор» (к сожалению утраченного ....), последовательности и размещении клавиш переключателя диапазонов и графики шкалы. Те же 4-е диапазона частот в тех же пределах по частоте. «Транзистор» немножко легче лампового предка, правда всего менее чем на килограмм - 3,1 кг вместо 4-х.
На очереди - сравнительные тесты с ламповыми предками. ))
