et you used is quite unreliable and will tend to develop bad contacts. There is a reason they are cheap... I would use a turned pin type socket instead, e g an Augat socket. They will not let you down. More expensive, but considering the work involved in replacing a socket and the risk of messing up the PCB, the cost is negligible. Jonas

or which measures the AC voltage across the capacitor. You then calibrate the meter by substituting known resistors for the capacitor under test and marking the dial of the meter appropriately. Manfred's design puts the capacitor in series with a known resistor instead, making the scale read in the other direction. There are lots of ESR meter designs on the net. Jonas
