My resources say otherwise, but, as I said, ymmv. I have been using a pair of tsr black glass '42s in my tp since April, and have a pair of Black Treasures on the way for mid Jan delivery. I'll share my own opinion when I have one. Alas, it will be limited to the MWTP circuit though- and that is where my own reports are coming from, as I said; friends who use these tubes in that application.
