Hey Guys,
It`s a really good article about these speakers congrats
However can you check the value of C4 which was stated as 0,1 uF, originally described as 105J 250V, I have found describtion on the internet which is translating this value as SPIRIT 1UF 250V 105J https://www.yoycart.com/Product/39623098822/ , any other source also gives the same values, there is a huge difference between 0,1 and 1uF, if there is mistake and capacitor hasn`t been measured by the author of post by himself its just a small reminder.
Kind Regards,
Daniel
