Re: UV Dry Film Photoresist PCB production info in 'Chinglish'!
this is for a " tube " amp of a well known site : Sound review
Overall all frequency are balanced, with the full tube flavor characteristics, the full sense and intensity of low frequency, IF is warm mellow, and it has a special advantage in high-frequency.
