Hello'
I have built a mic amp and wanted to check the wave form on a
scope but when I connect the probes to the o/p of the amp the power
supply trips (The Mic operates on 9 volt single rail.) I connected the
scopes ground probe to the -ve (common) and the output to the other
probe. the scope works alright with a signal generator. The Mic also
works on a power Amp but with some noise.
What might be the problem?
