Matched Pair Philips E88CC 6922 Gold Pins Dual Stage Getter Used tested NOS

One matched pair of rare  Philips E88CC / 6922. Gold pins, the same codes.

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

22/21 21/21 mA

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

Tested for mirophonics and low noise in RIAA preamp, and they work 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.
