I have read up on the subzero fix and I believe it would be the best solution to help protect the new laser I am about to put in my V12's. However, i cannot seem to find any schematics to learn how to make one myself. I am not trying to avoid paying for one (very cheap), but rather avoid waiting for one. If I just purchased the components locally and installed, it would save a lot of time.
So, can anyone point me to a schematic?
