    Hello, Thank you for your work and sharing
    Question: Is the coil paired with RD resistance? with the small fixture potensiometre 10 turns with a value of 10 Kilo ohms aisi than the other two resistors 2 Kilo ohms and 200 ohms to find the value of RD?
    Regards Gérard

      Hello my friend. I believe that you might want to watch my 2 videos on Damping Resistors. Here is a link.:

    Hiya Alec, Nice presentation once again! Still not heard whether Andy (Silverdog) has received his pcb's yet so I doubt will be starting mine just yet. Still contending with the Crossbow at the moment!,,Lol. Take care for now, Marty.

    Hi Alec,
    Very nice of you all these videos.
    I keep getting the 1000uF(25V) capacitor blow up, are you using high voltage capacitors ?

      No, I used 25V for C1. You need to check your transmitter portion of the circuit, you most likely have a short.

    if I used CA3140 can i chang same Risistor ,to get 0V ?

    i culd not get 0 V in TP 6 , when I turn the trimmer the voltage always 0 ,, that's mean taht the ne5534 dosn't work ,after i changed 2 Type of them ,then i placed in its place ,CA3140 ,, the votage changed but i culd not get 0 volt ,,when I turn the trimmer the Voltage redus at 1.2 V then its rise up again
