Ariel, There are very few places to check resistance. You should find a high resistance at all pins of the LM386 (except perhaps pin 6 which is the voltage rail and pin 4 which is ground.
Note that all other pins have a capacitor and that will stop DC continuity - therefore giving a high resistance reading. The best way to check it is to apply a sine wave (tune to a steady carrier) to the input and look with a 'scope at pins 2, 3 and 5. 73, Don W3FPR On 10/11/2012 10:30 AM, Ariel Jacala wrote: > Using the N0SS printed circuit board I am using the plans Don Wilhelm > published in August 2009.
