    hi kt315 ,
    test all accumulators - this is your problem! one AA size unit must give you 9-10 A of current on your digital tester in full charged state!
    please if you can explaine me more , i am a beginner and many thanks..................
    i see your photo ....what the diffirence deep by TM808 and your DP?

    hi rajesh,
    0.5mm wire #24 awg, i hope this site help you
    AWG Wire size chart and ampacity table for design engineers including skin depth frequencies and tensile strength data; electrical cable size

    good luck

    this is good or not ?

    if your DP is working good with this coil then this is good. much people did according this thread info and had got only unstable working schematic! so what my suggestions will cost now for you if you do nothing? from nothing you will get ONLY nothing! if you do anything you get the expirience and more info than I am able to give it you now and in the future!

    my DP work stable but poor detecting ,a canet koka 40 cm..........verry poor ..........
    with : R5=2.2k 1w ; R6=680R ; R23,24,25,26=4k7 5% ; D4=TL071 i didn't find LF357 ; C30=10.000uf ; irf840
    coil=40cm diameter ,23tr ,0.50mm wire , resistance 2.6R
    thanks for helping

    Abot changing values on caps, cona this solve inestability on delta pulse?
    My case is that some Delpa Pulse that i had build, have the problem of inestability, when you play with some controls like delay or threshold too.
    Any way the detector keeps goood power detection, but has i said in some setup situations it gets somoe inestability.
    Any ideas.
    Thanks my friend

    hi Nelson. thinking it is normal you will get the sound increase if you turn/play the controls, especially in increase of their value side. DP is very sensitive STATIC schematic and every such action will give the sound increase. on every the turn/tune I also push the knob RESET. I get an unstability if the battery already has been discharged after some work. now I go with 300 us of POWER PULSE WIDTH.
    trully

    i find a mistake in compesant 1.5nf , now my DP is better it can detect a canet coka at 85cm , but is not stable
    thanks for helping

    yes, certainly you can use 1,2-2,2 nF and the PC power supply. I use power supply from a modem for test and battery charge, with -5 and +12 V output.

    17 inch coil for delta pluse

    hi kt 315 what mean to say elaborted actually i need to know which guage of wire you are used 25 turns is about right for this coil with a 53.5" perimeter. This is equal to a 17" round coil.....rajesh
