This is probably the ultimate 12SN7 vacuum tube, the very rare Bendix Red Bank made 2C50.  These were made under contract for Raytheon for the US Navy and have the Navy marking on the base.  It has the Bendix tan micanol base, the short black plates and the top D getter.  The tube is new old stock, and will work in place of any 12SN7 or even 6SN7 type tube.  We have a number of these in stock, so the picture is representative.  Tested as unused on Hickok USM118B, and has 1950s date code.  These are $60.00 on our web page but we are selling a few on eBay at a discount.  MATCHED PAIRS ARE AVAILABLE, JUST $49.99 PER ADDITIONAL TUBE.  MENTION THIS WHEN YOU PURCHASE.  Satisfaction guaranteed.  IL residents pay 10% tax, outside of IL there is no tax.  We ship worldwide, all shipping is by first class mail only.
