Tung-Sol ONE (1) 5Y3GT rectifier AT1000 TESTED Vacuum Tube 5Y3 Audio 1939-1966

This listing is for one (1) 5Y3GT rectifier 5Y3 vacuum tube in the straight-walled glass tube shape. It has a black bakelite octal base, black or grey plate, and top, side, or bottom getter. Some of our stock is re-labeled or marked with the OEM of Emerson. If you're looking for a particular brand, please message right as you order - we pack and ship quickly!

Your tube has been fully tested on a computer-regulated, USA-made Amplitrex AT1000 with used good results. It has also passed shorts and gas tests. The tube might have mechanical wear or have the label rubbed off - these are very old! Tubes that test like new (tNOS) are available in a separate listing. Every tNOS or Used Good tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!
