Hello diyaudio members, Few months ago I repair a amplifier which have input selector circuit with 4 individual push button for 4source channel. I like that idea. Best thing of this circuit is if your 1st input source active and you wanna 3ed source channel just push 3ed push button, no need go through from 2nd channel just like as selector with pot.
Therefore I search this type circuit on NET I found Rod Elliott's Project 163. I decided to make CD4013 input selector PCB layout and test. It's working but not fully.
If you guys have other working ideas please share in forum, may be it's helpful those members who wanna make these type input selector in future.
I post few picture below
