In a perfect world you could not buy anything but Alpha-Core foil inductors.  If you wish to hear me elaborate on the minimal skin loss, low FM distortion, high-Q, low hysteresis or the great construction like the 4/9s pure Copper foil, you may call me.  If you wish to hear the music.......this is your coil!  For custom values, merely price the next higher value.  16ga. and 14ga. measure approx. 1.42" in height; 12ga.....2.0".

  
     
 

NOTICE - Alpha-Core increased their inductor prices again on August 8th. This is the second time in six months.  Sonic Craft is discontinuing Alpha-Core inductors, so as inventory is depleted, values will be removed from below.
