Got this quad in my Cryoset auction lot. They appeared to be unused though the boxes seem a little scruffy. I tested them on my Sencore Mighty-Mite VII for Emission, Grid Leakage and Shorts and all four passed with flying colors. I then put them in my Quicksilver GLA and listened for a few hours (maybe 6 hours total?). No issues at all.
$80 shipped US.
