I have a couple of their tubes, one is a like new 10BP4 in an 8TS30, the other is a 12LP4 that's been rejuvenated I think.
Edit, just retested the 10BP4 and emissions and cutoff are great but it shows a little bit of G1 leakage, about 11 volts and the scale on the tester says about 5 is acceptable, I'm guessing it'll still work ok though, could be some conductivity in the base glue too.
