Bought these from Watford valves a few months back but never used because it turned out a power tube was faulty on my amp, not the pre-amp. Selling as a set of 5.

Welcome to Vacuum Tube Depot llc! We have been one of the leading online suppliers of vacuum tubes for many years. Recently, we acquired a very large collection of tubes that we are excited to offer. We have tested and sold thousands of these tubes, and have many, many more to sell. After testing literally thousands of tubes from this collection, we have found only a small handful that did not test well. The vast majority tested strong. Buy with confidence, and if you are not happy with your purchase, you can send it back on your dime for a refund. We will combine shipping on multiple purchases within 5 days of the first auction ending. Payment must be made within 5 days or your purchase will be canceled and re-listed. We do not have the space to hold onto auctions for you for any longer than this. If you would like combined shipping, please wait to make payment until after we have sent your invoice. We send invoices each day after all auctions have ended for that day. Combined shipping can only be combined with this shop, not other shops with similar names. Thank you for shopping with Vacuum Tube Depot llc!
