Yes, I had the back cover on.![]()
It works now. After replacing Q4-Q10 with 2N3904s, everything is running smoothly. What I don't understand is why the Harbinger 1.5 and even 2.0 still use 2N5088s. Maybe I got a bad batch, but they were definitely the cause. According to the transistor tester, they're all fine. Annoying, because the device would have worked from the start...
Anyway, never mind, now I have a working device.
Thanks for your thoughts and contributions.
Holger
