2022年1月16日 · I stumbled upon Bob Cordell's KT88 amplifier presented in Linear Audio. I really like this design and I decided to give it a go. He uses the kt88s in pentode mode and I will use them both in pentode and ul mode. I already have the tubes but now I'm looking at buying the transformers and I'm in a bit o a pickle.

另一个是国内一烧友制作KT88推挽机的DIY作品。 这套件的电路，前面讲了，是4级放大；4路输入选择；音量控制是带马达的遥控方式；后级功率放大能在三级管接法和超线性接法之间通过继电器切换；另外，栅级负偏压的监测调节也是4路切换。 总之，各种小板很多，仅供电电路的布线就够喝一壶的了。 老法子，先把电源部分弄起来吧。 首先先布好4只KT88管子的灯丝线。 原厂的电源高压滤波部分是这么处理的，个人不太喜欢，准备调整一下。 用环氧板制作了一个横条，利 …

2010年5月14日 · hifidiy论坛-一直比较喜欢kt88与kt90三极管接法的单端，尽管在功率上有所损失但比较耐听。 做过几台J版设计的纯二单端机，对J版的设计理念及电路充满相信。

For a single channel, I need 2 tubes, 1 bias power-supply, a highly regulated power supply and a phase shifter .. For the tubes, I decided to use some KT88. In fact, a friend give me a spare matched quad of NOS (plain old) Gold Lion tubes + the needed output transformers so .. This tube are really great for the HIFI. And they look really great !!!
