Not sure how many hours they've been going for, as they came used with the WA6 I bought. It's working perfectly fine and are the best tubes I've heard for my WA6 - much better than the sophia princess, which I have already sold. No physical scarring or blemishes.
Price is $--- paypalled and posted in Australia. Willing to post overseas but will need to calculate shipping accordingly.
Happy to answer any questions, and thanks for looking!
edit* back for sale, sorry I haven't been on the forums for a while!!
