Klausmobile Tube Tester Files
The tube looks like a copy of 6N1P inside... beware, it's a radio frequency tube and likes oscillating, although quite easy to tame (low transconductance). But at low frequencies, at least on the charts, it looks exactly like 6N1P.
Legend: White curves: Ig<5uA Yellow: 5<Ig<20uA Red: 20<Ig<300uA. Measurements terminate at Ig>300uA
