You can use a capacitance meter to measure them but you will have to remove them from the circuit.
Dahlquist DQ-10 capacitor values?
All the caps which I want to replace in my DQ-10's have no value's.They all have their own numbers starting with DQ,such as DQ1065 (just for example).The only info.that I understand is they also give their voltage rating.Would someone out there have this info.,and any other suggestions for the crossovers that they could pass along ?I'm also looking for the best bang for the buck caps suggestion.Thanks to all in advance.
