TUBES - 2K50 Reflex Kylstron - WE / Bell Labs Perhaps something for your vintage tube collection ?? This 2K50 is labeled: Western Electric 2K50 NE826 - Bell Tel. Labs - Pre-Production. Excellent cosmetic condition — As I cannot test it, selling as display piece. Designed as a K band oscillator (10mW output) in the mid/late 1930s. 2K50 saw service during the WWII era and beyond. I’ve seen many examples from Bendix Corp., in the past but only a few with the Bell Labs labeling… Price: $25.00 shipped CONUS - PayPal / USPS MO preferred - Check OK, but no ship until clears.
