Sansui 2000, transistors question

thiemdx said:
Để làm triệt tiếng ồn trong máy sansui 2000, 2000a, 2000X các bạn xử lý như sau:
Các kỹ sư Nhật đã mắc sai lầm cơ bản, khi tôi mua 2000a đã phát hiện ra sai lầm này. Hãy tìm tụ C004, 1000Mf, 50V, dò ngược về gốc dây dương (+) tại F-1195 nối chân mày với mát máy (-) qua tụ, chỉ cần 1 tụ 2200mF 50 V, mọi vấn đề về ồn sẽ được giải quyết.

me too , the first thing i saw was surprise and shouted wtf . why are they so crazy:biggrin:
and if we can't move the capacitor closer to the power board because there is no space. why don't we move the diode next to the big capacitor and after the filter capacitor has done its job of smoothing the current, we wire it to the power board.
