Watts Abundant offers a really nice, effective, and easy to install output relay for the Phase Linear 400. Don Imlay has devised this nice little tweak which offers many advantages, including protecting speakers from DC. It works with both the Series 1 and Series II PL 400 amps. I got this kit from Don for only $89.00 and it includes new output binding posts.
The installation took me about an hour and requires some simple soldering to complete. The directions are quite detailed and easy to follow.
I have enclosed Don's detailed summary below of what this tweak does.
For those who have the PL 400, this is an invaluable upgrade providing peace of mind. Phase Linear opted against providing an output relay with their amps due to cost. Now's your chance to get an easy to install unit. Highly recommended.
