This is a very rare type of 6DJ8 or ECC88 vacuum tube.  It is a Holland made by Amperex for Valvo.  It is date coded 1957 and has both the rare top D shape getter and the indented glass middle called pinch waist.  These tubes sound fantastic in audio applications.  It will work in place of any 6DJ8, 6922, or 7308.  It tests good at 64-63 on our Triplett tester.  Satisfaction guaranteed.  IL residents pay 10% tax, outside of IL there is no tax unless your state collects internet tax, which will be collected by eBay.  We ship worldwide, all shipping is by first class mail only.
