I have always loved the sound of Phase Linear's. Many years when using a series 1 400 the output went DC and put 70 volts through the voice coil of a 2202.
So I am somewhat wary of using a series 2 Phase 400 for my 1400 Arrays.
Question is how to make the amp more reliable? New caps and transistors? Or maybe some device on the output that senses DC voltage and disconnects the speakers before it can do damage - is there such a device? Not that concerned about the amp - just the speakers.
There is great depth of knowledge on this site and any help would be appreciated.
