Purchased from Grant Fidelity as a backup pair for an amplifier that came with a pair of the same tubes as an upgrade option – both pairs were upgrades relative to the basic grade of 300B Treasures. After purchase, I used each pair for approximately 100 hours to ensure no early failures, then put this pair back in their boxes, where they have since remained.
At my asking price, I’ll include shipping and PayPal
