U4lU6K Is anybody strong in radio here? We need a colleague who would tell us briefly about the transistor T2. I hope there are radio amateurs here. If it`s not on the subject at all, then I`m sorry. I have to write because I have no choice. PS: if the spelling is not right then also I'm sorry, I'm just 13 years old!...
