Oh wow, let me know what you think! I may have to buy a pair and check 'em out for myself!
I have a pair of original Tung Sol 6550 tubes. Not NOS 'cause I use 'em from time to time. But I treat them like they are precious family China. Not for use every day. Not even for every Christmas. Only for Christmas' when royalty visits. LOL!
And I have a bunch of Mullard 12AX7 tubes, which I have found that I like a lot. So I'd be happy to try Mullard KT88s. Not sure how I missed those before now. Somehow, I looked right passed 'em, I guess.
Will do Wayne. A friend had a used pair of 6 year old reissue Mullard KT88s
and they do spark my interest. Auditioned and the bass was less but tight,
maybe too tight, but then the M pair are somewhat used.
I can always tweak my monoblocks to increase bass (accuracy/naturalness)
if the new ones are a little light.
The 1,000 hour reissue Tung Sol 6550s had the same idle cathode current as
the other quad new TS in the boxes, was impressed, but then one of the used
TS started arcing with only ~440 p to k volts, 70 ma.
Besides that the TS side getters were pretty much used up, while the used
M had virtually no side getter deterioration.
Will be a little time to test, get some hours, but will report back Wayne.

I just found a couple of selections from Anna Lapwood, Prince Albert Hall,
London. Had forgotten how majestic a pipe organ can sound. The first is a
cover of the Da Vinci Code.
