FS: (2) NOS TUNG-SOL JAN-CTL- 5998 tubes with matching codes. I purchased these NOS as part of a bulk pack so no original TUNG-SOL boxes but will be put in standard white tube boxes. These tubes were tested at 108/109 and 109/109 where the minimum reading on the tester for these tubes is 70. I used each tube in my amp for about 5 hours to make sure they were ok and they worked fine. Price includes PayPal fee and shipping in the continental USA. I can ship either UPS or USPS if you have a preference. PM me with any questions.
