I have no idea what to charge for these tubes. I was thinking $500.00 but am open to reasonable offers. The tubes are approximately 10 years old but has had approximately 500 hours on them. I have no way of testing these tubes so as a result I would agree to ship them to any interested person/s and they could test them and listen to them and decide if they want them or not.The only cost to you then would be to ship them back to me if they are not to your likings. About me I live on the little island of Barbados in the caribbean.
