Hey!
I built this one last night but get a huge hissing / high frequency sound with almost all potential transistors I have in stock. 2n2222 and 2n5088 is huge noise/high frequency hiss. If I change it to for instance 2n2222 and MP39b it noisy, hummy.
Any idea what it could be? Or isn't it verified yet and might it be a bug?
