Here's the result - first w/o tubes I fired up the Centau. All lights on and
not blown fuses. pit in one tube that did not look bad - blew the fuses -
tossed that tube out, alonng with the one that had white dus in what looked
like a volcano in the stem. Put in last tube - all fine lit up. So, tossed in
the two Svetlanas with the sole Taylor. The mixed troika lit up and gives full
power. This AM ran it at 3/4 power (a tad less than 75 watts in) and had good
reports and it was a happy camper (so was I).
I'll order a set of matched tubes today so when this troika blows I will be
able to start fresh - but, in the meanwhile, what is there to loose?
Many thanks for the suggestions,

Ok, guys, here is the scoop.
My trusty Centaur seldom needs to be re-tubed, BUT now I have two pairs of
tubes, one pair Taylor, and the other pair Svetlana because over time one tube
left the troika for the electronic dump. Yes, matched tubes are the ideal,
but having a couple of pairs sitting around doing nothing for me and no
foreseeable makes me wonder. Just what would happen if they were a mixed
troika. That would leave one tube in the bin ready for another time.
Any ideas on dire consequences?
Many thanks,
