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! We have tons of these flats loaded with tubes. We opened maybe tons boxes to make sure tubes matched the boxes, out of all the boxes we opened. Most matched, but several had the correct number but different brand from box. Sold as is

I took this off of a Coronado C800 radio that worked, but the wind knocked the radio over and damaged up to where it wouldnt sell, so I removed all of the tubes. It picked a lot of different radio kind of signals. I did not get feeds on most of the other radio signals, but the regular radio worked. We live in fargo North Dakota and we dont have as many radio networks here, and I question if we have the signals that should come up even do in our area. I am not sure if this are used for regular radio signals or not though. If you know what they are for and want to tell me, I will try to update the listing if you want to tell me. I will combine ship if you want another item also.
