Default Black out coused demage in tube output stage

I would like some help regarding my tube amp. - it is amp for hifi stereo
Well,what happened.During I was listening the amp,the black out occurred
- when the electricity came,I connected again my stereo tube amp but I noticed that the music picture is not the same - the bass was not so mighty like before and the whole music picture went a little bit back.In the same time I noticed that the power transformer is getting much warmer then before - the amp has 70 w in push pull amplification.One more thing.The sound is now more clear.High frequencies are more to hear as You put on treble regulation 2-3 db.The space is not more deep like it was before - ok this are some more observation regarding sound.the model is A 100 T from Cayin having 8 kt88 in output stage
.Do You have any idea what that might be??.I think the only thing that could happened that some capacity got shock.Can anybody let me know what part of amp. is possibly damaged?

That is absolutely impossible to guess at a distance. Provided that you are convinced the phenomena is real (make sure it is not the particular source) please find a good service tech who specializes in tube gear and have him look at it.

Shut it off and listen to it tomorrow with some tracks you are very familiar with. Maybe your mind is playing tricks with you ! Maybe.....
