I recently had a kid come over and crush a dome on my T8s. (two of them actually)
I had a HARD time finding a replacement. I ended up finding an entire CASE of these tweeters from someone selling out a warehouse.
I have 7 brand new perfect spares. These are the original Vifa D26AG 38-04. I have no qualms keeping the whole stack of them for myself, as I have replaced a total of FIVE tweeters in my Trancendence 5 channel system over the course of a decade.
On the other hand, I could put a couple up for sale in the classifieds if there are any Hales owners missing a tweeter. I would be willing to list as many as three of them, if people are in a jam.
I was incredibly lucky to find these and was starting to panic. So I can imagine I was not the only one.
