Sold: One matched pair of NOS Raytheon 5814 tubes in original boxes. These cryo-treated tubes from 1953 feature black plates and square getters. I purchased two sets of matched pairs of these tubes from a reputable dealer several years ago for use in a pre-amp and this pair was kept as a backup pair – never used.
The fragile red lettering is completely worn off on one tube and partially worn off on the other. One end flap on one box is missing.
Dealer test results as marked on the boxes:
Tube #1: 21.0/20.9 - VLNM
Tube #2: 21.0/20.9 - VLNM
Sold USPS Priority Mail with Insurance and Tracking/Delivery Confirmation. Shipping to US addresses only.
