Detin un amplificator de chitara Hartke B30 care are o problema: difuzorul pocneste la pornire. Nu detin o schema clara, am gasit doar una neinteligibila, insa din cate mi-am dat seama acest amplificator nu are protectie pe difuzor. As avea si o intrebare, pentru protectia difuzorului se poate pune un timer banal cu un 555 care sa-l cupleze dupa cateva secunde sau e mai complicata problema?

Foloseste un timer cu unul sau doua tranzistoare, de ala banal, cu un releu si ai rezolvat problema.
