I love these tubes but have questionable & unpopular opinions about many things.  For instance at Decfest I wasn’t impressed at all with DT’s big Metal baffled OB’s or the DFH”mother-in-laws.” Glad to hear that the latter has new drivers. Ask for the “Ralph Kortyna “ discount as opposed to the Decware one if you talk to Don, he will explain. I hope this isn’t the straw that breaks the camel’s back & gets me banned. I guessing from where you’re posting this you want used ones, so good luck.
