Hi
I am building a protodac. I have just soldered an audionote kaisai non polar capacitor 2200uf in position c3, c4 in place of the suggested two 1000uf parallel electrolytics. I am testing components before insertion with either a Peak atlas gold esr meter or a multimeter. I measured the cap before insertion with the esr meter and it was showing correct value with zero esr.
After soldering in it was reading no value only saying in circuit/leaky.
Can anyone advise please if the cap has gone bad due to the heat during soldering. I did in fact use heatsink clips whilst soldering. Or is it in fact because it is in circuit. The only other components on the board though are a socket for the module and the five resistors.
Would it be advisable to replace the cap now or leave it until the build is completed and maybe doesn't work and perhaps cause damage. I do have two panasonic 1000uf to replace it with if neccessary.
