Just a notice that there is a Tungsol labeled 5998 listed on e-pay for $78 buy it now. I have no affiliation with the seller whatsoever aside from having purchased an inexpensive tube or two from him in the past with no problems. $78 is still steep for a 5998, especially one that doesnt appear to be NOS but atleast it's not astronomical relative to most of the 5998 prices Ive seen over the past year or so. Again, this is just a notification in case anyone has been looking. Im not supplying a link, ebay search will easily pull it up along with just a few other listings.
If not appropriate to post this, my feelings wont be hurt if it's deleted or moved
