VINTAGE SYLVANIA 3DB3-3CY3 CLOSELY MATCHED SET OF 3 NOS TUBES *TESTED*

Description

**Tubes are described and tested to the best of my ability, subject to the limitations of the equipment that I have available. The pictures you see are the exact tubes that will be sent to you. Test results are likely to vary some between your equipment and mine due to the imprecise nature of 60-year-old test equipment. Tubes are not tested for noise or microphonics. These tubes are new old stock that we personally bought new decades ago. Please understand that these tubes are sold as is, since once the tubes leave my possession, they are no longer new old stock. Therefore I do not accept returns. If there is an issue, please let me know immediately so we can remedy it. **
