These are drop-in compatible with 5Y3 using a 4-pin to octal adapter, available on Reverb.
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 tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!
