I built a testrig/probe like jkokura described.
Is it supposed to be noisy?
Is there any point in making the probe/out switchable?
mine also, some sort noisy, but I try to shield the ground and the Input jack (all tip), reduce a little bit but still have a noisy sound
I used acrylic boxing (I made one for testing).
also try to put the ground alligator jack to the DC 9VDC Ground, it will reduce a lil bit the noisy sound too..
