It seems you know very little about electronics.Who would like to discuss that?

[ZOUjiarui]

No, the 4066 improvements work perfectly, I've seen videos, more than one.
I don't want to discuss bf245 and 4066 now. What I want to do now is to copy this business in China 5196:6103.

[Andi68]

What's your problem?There are versions of this circuit that work."4066 replaces bf245" what nonsense

[ZOUjiarui]

Trash 6103,Rubbish 6103, which dog made the fake drawings?

[ZOUjiarui]

Can anyone tell me what's wrong with this circuit diagram?Or no problem, just this C39 error.
