2012年12月2日 · I have a plan of building 2E22 SE ampli. Could anyone give me specs and plate curves of this tube in triode mode. Thank you and regards,

2013年1月3日 · I did build 2E22 SE amp with AC filament (because I like AC for filament 🙂). Sound is so sweet and warm. Hum is > 13mVac, so I can hear them at my chair. I intend to take an …

2021年6月15日 · 我仔细查了2e22与2e24均是五极管，2e30才是束射管。 两个电路有差别，栅极与帘栅之间，一个接稳压二极管，一个接电解电容；其交、直流情形会有不同。

目前音质不如我做的fu-50推挽，不过2e22中高频段的表现，确实值得挖掘。 目前校音工作还在继续进行。 感觉整个电路增益太大，电位器在10点钟位置已经开始过载。 屏至屏反馈不接的 …

The 2E22 is a 30W dissipation pentode, but output power remains basically the same as the other pentodes/beam tetrodes mentioned, since the output power is limited by the voltage across …

The 2E22 is a directly heater pentode for RF power applications. It looks similar to the indirectly heated 807 but operates at higher voltages and produces more power. The ceramic insulators …

2024年3月28日 · I found a 2E22 model in the Spice Model thread, I have no idea how good is. Then I changed the voltage dropping resistors, to get the right DC values and take into …
