I looked at a set of SED KT88s out of a McIntosh MC2000 recently. The owner had a operation time clock on the amp. That is a novel idea by the way. With a little over 8000 hours on them they all tested like new on a 539B. Two of the 12at7 were weak though and hit the dumpster.
I have seen similar life results on the SED 6550c also.Ron-C
