Shipping
I do combine shipping. If you are an International Customer, please contact me with your intentions BEFORE YOU CHECK OUT. The terms are fairly basic. If your order is less than 8 ounces(with packaging), you will only be charged the initial postage(for one). I can generally fit six or so smaller tubes, or two larger ones in the packaging and still come in under 8 ounces.  If it exceeds 8 ounces I will work with you on the cost of postage. Just PLEASE LET ME KNOW BEFORE YOU PAY. I will send you a revised invoice indicating  the adjusted shipping costs.
I pack my tubes in a sturdy 7"X6"X5" box, utilizing quality packing paper, bubble wrap and tape. This packaging weighs 4 ounces on it's own, and I will not cut back on that to save space/money. The tubes need to get to you in one piece.
About Us
I'm a bit "Old School", and prefer a handshake to a "click". But this the way of the world now. So I try to incorporate as much personal service as I can through the means at hand. I see and handle every tube that comes through this store. If a mistake is made(and it does happen), I immediately own up to it and take care of the problem as fast and thoroughly as possible. We now have some more space allocated to our "lab", where we test every tube on one of a growing number of excellent tube testers, including a Hickok TV-10A/U, Hickok 539 and a Heathkit IT-17. I am excited about the GIANT NEW COLLECTION(50,000 Tubes) that came in from Scranton, Pennsylvania in April of this year(2018): added to what we already had, and what's coming this Fall,  I look forward to playing matchmaker with the substantial variety of tubes I now have. We are always looking to buy more tubes. Large collections, small collections, it doesn't matter. If you have some to sell, let me know, and we'll see if we can work something out.  As always, please feel free to ask any questions you might have. Looking forward to hearing from you, Dan.
