I've been cleaning out my basement, and ran across two pairs of unused Groove Tubes KT-66HP tubes still in the boxes. As I recall, they were fairly highly regarded a few years ago, which is why I bought them for my Bluesbreaker. I've since sold the amp, so I don't have a need for them. I'm planning on offering them for sale on eBay, and was hoping you all could give me an idea what they may be worth. I don't wanna rape any potential buyers, but I also don't want to just give them away. What do you think a fair asking price would be?
Thanks,
Brad
