I have a bunch of extra tubes here that I don't want to list on eBay and I need to make some room in this house for a new member. If you are looking for something not listed here, let me know. Maybe you can use some of the singles as backups? PRICES SHIPPED Results in % of NOS of GM as tested an Amplitrex AT1000 (all test results on boxes).
