Up for sale is a matched pair (2 pieces) of ultra-rare WWII era Ken-Rad JAN-CKR 6J5GT/G VT-94D single triode vacuum tubes, brand new in their original government contracting boxes (Accepted July 1940). Made in the USA, these military-grade tubes feature iconic black plates, unique leaf getters, and durable metal base  with military JAN stenciling. Renowned among audiophiles for producing rich bass impact, deep soundstages, and smooth high frequencies in vintage preamps and custom driver stages.

As shown, both tubes have been thoroughly tested on our laboratory-grade Amplitrex AT1000 tube tester. Plate current (Ip) and mutual conductance (uMhos) measurements alongside percentage performance ratings relative to nominal specs are detailed in the table below.
