hi,
Thanks for your feedback. We are happy that you like this circuit. 🙂
Hi. Lennie’s original design used a 2n4117 transistor and you have used a 2n3819 transistor in your updated design. Are these two transistors the same? Please explain. Thanks.
Hi,
Yes, it is the same N-Channel Silicon Junction Field-Effect Transistor, but it might operate differently. I apologize that I can not explain the details clearly yet, as I haven’t built this circuit myself. We’d like to experiment with this circuit in the future. We are thinking of Lennie and hope you’ll look forward to content about this circuit. Thank you for visiting our website. Again, I apologize if my English is not good enough.
Sincerely yours.
