Details:

Please understand that what you're buying is used unless its clearly stated as new. Its a nos new old stock, though not exactly new looking. A cursory check showed voltage s are fine; no reason to suspect any defects. In case you're curious about my username tungsten ware, heres the short version: I live on tungsten drive, and this connection is not a coincident.

I charge for actual shipping only .e. Tungsten, known for its remarkable properties and versatility, finds extensive application across various industries, ranging from manufacturing construction to electronics healthcare. Tungsten wires and filaments are commonly used in incandescent light bulbs, electron tubes, electrical contacts due to their ability withstand high temperatures maintain consistent performance. Photos are an integral part of my s: please view all photos carefully.

This was an exact replacement unit for a Daven tube tester can't remember the model something closely related to / us army signal corp i-177-b dynamic mutual conductance tester if not this model. This transformer has obvious signs of handling, but most this is paint flaking off due to age and not having been in a box. Buyer pays actual shipping on 6 lbs. Please view all photos, as they're better descriptors than my writing.

Works great, and could be fantastic for a tester of sorts. What you see in the photos is exactly what you're buying on. Transformer weighs just over 5 lbs. This listing is for an unused Utc E-4113 multi-tap / multi- voltage transformer tube tester.
