[QUOTE="SteelPat, post: 361738, member: 4467"] Because you are using the common ground of power to detector and to the amplifier you may need to isolate the output of detector to the input of the amp. You may find that the 'ground' of the headphone output on detector is lifted from the power ground. Easiest way to tell is use a 9v battery just to power amp module and see how that works. [/QUOTE]
