Self-made Tube Amp 自制胆機同好會

有興趣自制胆機. 正在學習中. 有無高手教路. 2A3 定 300B 容易做D?

No matter 2A3 or 300b, it's no big different. Once you understand the theory, there's no difficult at all. Careful & patience are most important, espically the high voltage, it will kill you!! Enjoy DIY!!

gijoe_22講得好o岩，一里通百里明，不過 300B 既套件就勁貴，而且膽座大，開孔方面會吃力 dd！

Thanks for your comments! Interested to take the DIY course in the next time to learn more from you all!

Tiger, your 300B looks great, what is the total cost of making it?

Tiger 師兄，支 VR 一定要換級進，會有大幅度提升喎！不妨試下。

Hi don't me 師兄,受之有愧.
  Goofy 兄,total cost of making it about $3500 左右.

  請各位指教

師兄，呢隻 VR 都幾 OK 喎！

Just want to share my work!

上面張300B線路圖還可以改良，加強低音的改善，致於開孔方面用鈴梳基本是沒有太大的分別！機箱用全鋁的會比較好做，會貴很多，但！物有所值！
