That looks amazing and so unusual. You are lucky to own one!
Thanks

Well, funny you should ask that. As it happens, I do indeed :)
Picture below - different operating conditions than the DK25 image, so
this one is spinning in a way that emphasises the main cathodes.
With regard to data on the Rodan tubes, the link I have to a PDF is
giving me a 404 tonight - I'll need to prompt the site owner to fix
that. But electrically the base-6 and base-8 tubes are identical to
the DK24. Put 380V+ on the anode, operating current around 500uA and
feed them guide pulses of 100V. They're pretty tolerant tubes.
Jon.
