I'm not sure how relevant this is to the 845's, but I just had a monster quest for PX25 tubes, which are much more scarce.....
I heard from a couple reputable sources that the KR tubes are not of the same quality now that Dr Kron has died. This was confirmed when I went ahead and bought a new pair of their PX25's - they're pretty much the only game in town for new production on these. It turned out that they weren't as robust in construction, and they didn't sound as good as my pair from a few years ago.
I'd be interested to hear if the 845's are also on the decline...
