Hello, I have bought an amplifier shown below.However when I am trying to test if my VDD is shorted to GND my measuring i get the DMM beeping as if the VDD is shorted to GND. ash shown in the layout below
Also when I measied the resistance across C2 capacitor I see only 1.6ohm.
DId I get a faulty component?
Thanks.
A video of me doing the test is attached in the link.
Thanks.
