There are a couple of diagrams here. What are your asking? You’re better off hand wiring it, a board most likely will create oscillation because the traces are so close. Ask me how I know. 🤣
One of my favs. Now build the current lover, the Fraudhacker and the Kingmaker. I went on a Flanger tear, but there aren’t quite as many of them as there are phasers.
The only thing I can think of is the layout is wrong. In my experience, some of the schematics are wrong. My guess is intentionally. It took me a couple of weeks to figure out why the reverb was operating in reverse.
