No....
At this video is Morgan, not Esteban. It is taken on 2008.
Esteban never saw or touch this PD, he said it so many times at RS.

as you did travel to portugal ..my question , saw in two movies Alonso black Pd when set threshold only orange LED turn on. Why green LED is off ?
as in circuit when rotate metal detector threshold pot. must be turn on green LED .!!!

I don't remember the leds , but there was a problem.
If u will see the Qiaozhi schematic u will see that when the green led is turn on the current flows through d6 and T16 so the voltage is hight and the led burning. A resistance in series with led will protect it. So when u see video where led don't light then it is burnt.

your opinion is green LED damaged

[Geo]

yes....

My advice is to don't lose your time with pd.
There are n't all the secrets in forum.
