sửa ampli Powersoft K20. 18000w

[@Siang_mallam]

Nếu không có đầu ra thì nên kiểm tra cái nào?

[@DuyNguyen-xi7sd]

xem nh video của ad mới biết powersoft ko bền như lời đồn của các video quảng cáo

em sai rồi. Đồ điện tử nào sài vĩnh viễn em.

Mỏng dính size 1u vậy mà 18kw 2 kênh. Thật quá khủng.

Great job. Do more videos like this. Your DIN mounted watt meter it's not working properly. 220V x 1.6A =352W not 176.

Hello, good video, I have a problem, with Powersoft K20 it was working normally and I got an "error 6300" message on channel 1, what could be the cause and its possible solution?

@@76139tins Greetings friend, not the coil, the source capacitors, how many uf are they?

[@izzzzzz6]

@@mastercell14 In my Q3002 they are 1800uf 100V x14 of them. If replacing with cheap components then take 2200 if they fit. Some of the newer components are smaller than the old capacitors in the earlier Powersoft series. On the older Powersoft amps you can now fit bigger value capacitors or smaller ones than the originals with the same value. Giving either more air flow and more spacing from hotter parts of the board or a slightly larger value in capacitance. When servicing older amps always check all of the capacitors value and esr. I just repaired c55 in my amp. it was short blowing d5 and r42 i think. There is a part of this video where he is working next to the big capacitor bank and those caps are 680uf 250V Also.. TAKE THE FRONT PANEL OFF AND CLEAN ALL THE DUST OUT OF THE FILTER! oops caps lock,...
