Restoration professional karaoke speaker / Rehabilitate step by step 

Asked twice and still no answer 😕 😒 😐

He uses acetone

Ele deixou um capacitor totalmente pelado dentro de uma das caixas sem trocar-lo ... Mais lindo o trabalho dele

Parece que ya las habían desarmado o algo así sino no se explica el deterioro de los parlantes que lástima suerte que los recupero es una lastima como la gente destruye parlantes porque si

I agree on a tech level. Replacement of a voice coil, cone, surround and dust cap effect the sound completely. If replacements are exactly as originals, them ok. But frakensteining parts and expecting it to sound like factory is foolhardy. BUT if these videos spark interest in repair and refurbishing, then great! Just as the expression Caveat Emptor appliers to purchase, there are similarities to repair. Just because it is on RU-vid does make it 100% right. I do like the fearlessness of Mr. Electricity, not to mention the chickens clucking!!

Да,для ВЧ динамиков,чтобы их не спалить)
