[QUOTE="1200GXman, post: 1027925, member: 17884"] So I managed to get the Arduino capacitor tester working. I received a couple of years ago a complete front face panel from VinylJan on the forum. Thanks again Jan. Wanted to keep it for the spares in case a pot or switch fail due to wear or age. I removed 2 capacitors that are similar to the coupling caps under my amps tubes and tested them. Again I would not trust the results as the caps are 40+ years old and are not receiving the volts that are being put through them in a tube based amp. The Arduino only uses 5V. the two I tested are 0.05uF 400V each and they tested 0.047uF and 0.044uF respectively. Again, just for interest sake. Wouldn't bet my amplifier's life on it. [member=772]handsome[/member] There is a project where you can make a ESR meter also with the Arduino. Think I will do that one next. Thanks [/QUOTE]
