现在的问题是要不要加2路反馈,或者只保留一路负反馈,实验时很难把0.22欧姆这路反馈調好,个人意见?是不要该反馈。特向大家请教 !
The current question is whether to add 2 channels of feedback or only keep 1 channel of negative feedback. It is difficult to adjust the 0.22 ohm feedback during the experiment. My personal opinion? Don't give feedback. I would like to ask for your advice!
 
该放大器声音的价值值得申请专利,完善后的电路做初步的PCB规划,论坛里有人能代理做专利吗?
The value of the amplifier sound
is worth applying for a patent,
