In my opinion, the original PD Alonso must also be unstable. In the films that you and Morgan recorded in Portugal.. all the films are only a few seconds and at most a minute... the PD is being processed and explored... there is no film that is being processed and explored for 10 minutes.
Yes, I have very precise measuring equipment.
The use of high-beta transistors in the form of Darlingtons is one of the reasons for the PD's instability.

My PD is very stable. I must turn it on and wait for 1 minute, after it i can adjust it and go.
At Portugal our purpose was to show that PD works and can catch the phenomeno. Our interest was not to show how much good was the PD.
The main problem was that it needed very critical adjustment.
