ECL82電路收集筆記
ECL82電路收集筆記 http://danyk.cz/elzes_en.html 引用 這種電路可以用多種ECL或PCL的管子,建議用200V以下至100V的電壓。 ECL (parallel) or PCL (serial) tubes. They contain preamplifier triode and power pentode in one tube. Vacuum tubes like PCL82, PCL84, PCL85, PCL86, ECL82, ECL84 or ECL86 can be used. I used PCL82 tubes with 16V 0.3 A heaters and an anode loss 7W max. The amplifier is powered from the mains transformer. Filament voltage selected according to tubes (for me 16V 0.6 A). Anode voltage of vacuum tubes is not critical, may be about 100 - 200V according to the desired power. 這個電路可以使用 PCL82、PCL84、PCL85、PCL86、ECL82、ECL84 或 ECL86 等真空管。 準備兩種電壓 16V 6V 就可以用PCL跟ECL系列的管子。這個電路真空管的屏極電壓並不重要,根據所需的功率可以在100-200V左右。(更高的電壓會提供更多的功率損耗會更高電流更高,這會導致更快的損壞管子。) 其他參考電路 https://el34world.com/Forum/index.php?topic=22686.0 引用 來自old italian Nuova Faro Record Player的電路 https://www.experimental-engineering.co.uk/2019/03/05/ecl82-amplifier-build/ 引用 https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fimg.pconline.com....
