Pair, Type 19, Dual Class B Power Triode Radio Tubes -Tested Very Strong
Pair type 19 radio tubes. Dual class B power triodes. Engraved bases. One is a Philco and the other a National Union. Both test at 120-120 on a Jackson 648 tester with 70-70 being lowest range for good. We also tested the tubes for leakage and shorts. With no problems at all. When you buy vacuum tubes, you want to make sure that they are good ones-we are proficient at using our testers, and have used them for many years, with few problems. Please look over the pics and be sure to ask questions. The winning bidder should contact us within 2 days of auctions end, with intentions, or we reserve the option to relist. Items will be shipped promptly(as business hours,and time allow, Monday-Friday) We do not work on weekends. We use USPS because it is so much easier for us; but you do have a few choices within the USA. I have found that even the ... morecheaper usps services(like first class and standard post) are just about as fast as priority mail these days-they all travel the same way, so it's all alike, really. International buyers should understand that items can take anywhere from 2 weeks to(although rare) 2 months-or more- to get to you. This is due to international customs services, and it is out of our hands. Purchasing extra tracking can be helpful for such instances, but that is up to you- if you wish that then you need to request it. Thank you for looking
