Thanks for your replies.
Well the caps that will be testet is in regular comsumer-electronic, like monitors, amplifiers, etc. The primary reason for buying this thing is because i have two NAD-amplfiers in bridge-mode. One of them are lower on output, and alot more noisy. I think this could be a bad cap or two? Anyway, it is allways good with new tools
I really dont know much about caps and frequency. But i can manage to replace dead ones. Just need to confirm that they are bad.
No problem with 50-100 USD. I just don't wanna buy something that does not do the job.
