@tonyjobson Hi ,
Sorry to hear that.
Would you please contact our customer service cservice@banggood.com?
Please send us your order number and a video or some pictures to show your problem.
ricardomagagnin Same problem, when I removed the Q1 the output goes to 15V. I really do not know how to solve it.
رد 29/10/2016Halmar I got 0.4VDC on output when I hooked mine up for testing the first time on a DC source. You have to use an AC transformer because there is a charge pump circuit to generate negative voltage for the Op-Amps.
