  • Golden mask 1+ coil help please

    Hi everyone
    does anyone know what the inductance and resistance is for a golden mask 1+ DD 10" coil is please?
    thanks

        Those coil's work's on all GM model's.
        Here is what i mean, in the first page...

        Quoted Ivconic post:

        A few words on coils...
        Those who already made attempt on "Wave" and "Admiral"; may not need additional infos on coil making.
        Pretty much the same story here... you may use the same coil data.
        Magnum TX&RX front ends are pretty tolerant and you may achieve nice results with variety of coils...
        But on Golden Mask version of coils there is pretty nice little thing that author of Golden Mask did!
        My hat down to that!
        There is additional winding or few, continuing from TX coil (over the TX coil too) and later fed up to sync demodulator.
        Depending on size of a coil; additional resistor maybe presented to.
        It's all about to trim a bit more precisely the phase and current for sync demodulator.
        So... you may wire up your coil either ways; the "traditional" one and the "Golden Mask" one.
        In second case you will achieve more precise and more stable Disc&GEB ranges, so i will rather suggest the second one, the way it was done at Golden Mask coils.
        Detector can run equally nice in frequency range; 8-18kHz (probably even a bit wider) with the same setup and the very same coil!
        Only thing what you have to do is to change the TX LC tank capacitor.
        Most common data for the coil are:
        - RX = 5mH - 7mH, 18 ohms - 30 ohms
        - TX = 0.6mH - 0.8mH, 2ohms - 4 ohms
        - TX capacitor = 100nF - 470nF
