Settings for ECC808 tube on 539c tester

I have some NOS Tungsram ECC808. I can't test on my Hickok 539C tube tester, because I not found correct settings. What is the good settings for this tube?

I have the latest test data book for the 539C, but an ECC808 is not listed. However, a 6KX8 is listed and is very similar. So I would test it as a 6KX8 and go from there.

6.3V EV-9708-6 1.3 .... P4 E 800 triode 1
6.3V EV-1302-6 1.3 .... P4 E 800 triode 2

According to this here ECC808 is pretty much the same as the good old 12AX7 (ECC83) but with a different pin-out. I hope that helps.
