Five NOS Brimar 13D5 Tubes. These are a premium 12AU7 type tube that I found to be nice upgrade in my Audio Note pre-amp. All five tubes were tested and matched by the original seller with the uniform measurements as 84.0/84.0. The labeling is very delicate and slightly worn from rubbing in the boxes. One pair was used for a few hours solely to test and evaluate in my equipment. The others are unused. Packaged in generic white boxes, the tubes offered are backups that I no longer need.$25.00 each or $100.00 for all five + $7.75 USPS Priority Mail 2 Day Shipping including Insurance and Tracking in the USA ONLY. PayPal or Money Order/Certified Check accepted for payment. Thanks for looking and please e-mail me with any questions.
