I come in and turn the 6505+ on and at first it sounds bland as hell. The midrange isnt smooth, the treble is like ice picks.

after 20 minutes it will start the transition which takes around 5 minutes. After the 25 minutes it sound godly. Smooth midrange, note definition kills and so on.

I understand that tube amps sound better as they warm up but out of all the tube amps Ive owned this amp is the most severe...

Maybe something wrong with it or is it normal?
 
I've owned 7 of them and never noticed anything like that.
 
I've had some real weird tube things happen, like a minute or two in, but 25 minutes? I assume youve tried tubes? :dunno:
 
I may be exaggerating on the time a bit. It feels like a long time but it happens in about about 3-4 minutes when I timed it.

It also did the same with my other set of tubes.

*ding ding ding*

Your ears will adjust, or just plain wear out, after a while, no matter how messed up something may sound to you at first. I'd assume the latter if you thought it sounded "like ice picks."
 
How long do typically let it warm up before flicking the standby? My JSX sounds cold briefly if I only let it warm up for a minute or two. Now I wait anywhere between 5 & 10 minutes.

That describes what Im getting.
 
My 5150 had a series of strange pops and noises about a minute after powering up from standby, I drove myself crazy with the power amp tubes, the local repair place couldn't figure it out with the help of Peavey on the phone, so I sent it out to Peavey and it turned out to be the PREAMP tubes......I don't know which postion did it. My 5150 has always eaten preamp tubes like crazy, I had gotten in the habit of replacing the first two evey three months, throwing away v1 and v5, putting the new tubes in 1 and 2 and moving everybody else down the line. This habit eliminated my unexpected and and inconvenient tube failure problem. Peavey did not seem at all concerned that I was having such problems with the preamp side. They said all that they did was just replace the 12ax7's, it was fixed.
This may be a hundred miles off the mark regarding your problem, but just sayin', 12ax7's are cheap....
