A cautionary tale...make of it what you will.
I have 4 ProtoDacs... 2 with the module soldered in place and 2 with the module pressed in to soldered headers.
Both soldered versions have failed. Low or no output on one channel.
Both pressed via headers perform fine.
From several posts on this and other threads I suspect the modules are very temperature (solder) sensitive and would suggest that using headers is beneficial.
Today I tried to desolder an errant module that was hardwired.
Would not recommend !
I finally managed to remove the module and replaced with headers and a new module.
I now suspect the soldered module was compromised from installation and had deteriorated prior to its dropout.
The replacement has all the life and sparkle of the original and with a now pressed fit I hope for it to continue as such.
However, I am now calendaring to unplug-replug modules in their newly installed headers and perhaps some Cramolin.
(have several modules in reserve just because)
