Amperex E88CC 6922 (Rare Curved D Getter) Used tested stronger than NOS 1960

Auction is for one rare  Amperex E88CC / 6922 rebranded RCA. This is early old curved D getter type with gold pins and gray shield and it's much better sounding than later types.

It is made in Amperex New York tube plant in 1960 and star is clearly visible on photos, 7L4 etched codes.

It is carefully tested on calibrated Metrix U61B tester  with 100V on plates and -1.5V on grids and results are:

21/21 mA

Value for 100% NOS tube is 16mA at this voltages! 

Tested for mirophonics and low noise in my preamp, and it works perfectly.

If you are looking at this listing, you surely know that this tube could be ultimate sub for ECC88 / E88CC / E188CC / E288CC / CCa / 6DJ8 / 6922 / 7308 / PCC88 / 7DJ8, as I personally checked in few amps and preamps, but please do not ask me about warranties how they will sound in your devices.
