My first new amp in well over a decade! An AC15C1 in white with a Celestion Creamback.

This is actually about a week late. Un-boxed the thing, looked fantastic. Turned it on real low and clean and started breaking in the speaker and it sounded pretty good.
So I get it warmed up good and plugged in my LP and crank the pre and the thing fell on it's face. Not smooth, no sustain, mega bright, weak bass and no thump, on top of that I had tube rattle once I Iayed the juice to the power tubes. Bitterly bummed out summed it up, a had played one in GC with a greenback and it had been pretty good. So now I have a day old amp I'm looking to dump.
Anyway so my bro says just play it for a week and put some new tubes in it. His AC30 a few years ago needed help too. So I commenced to beating on the speaker at high volume for a week and ordered a high gain JJ for the V1 and the rest are just a standard JJ set.
Now that the speaker isn't brand new it is sounding a little better, so tonight I re-tube it and it is sounding about 100% better. It's much quieter noise wise, sustains much better and is darker/warmer, excellent dynamics, no more tube rattle. Still getting used to it after being a triple rec. player most of my life but am having a lot more fun with it now. It may end up being a keeper after all once the speaker gets fully broken in.
