Well, I have about 60 hours on my Chardonnay now, and a couple nights ago it started sounding SUPER dynamic, real edgegy and hard.
I played with the gain controls for a while but they didn't help.
So I just turn it off and when to bed. I didn't want to start rolling tubes yet, but I suspected microphonics.
I am not sure why it would have just started after 60 hours when they should be getting better, not worse.
Anyway the next night I decided to roll the 6sn7, so I replaced the stock ones with a pair of RCA I had been using in my previous preamp, a AE3 DJH.
Well that did it, they tamed it dowm nicely, no more edgey runaway dynamics. Everything just smooth out and nice.
Now I cann't wait to roll the other tubes. I have some Golden Dragon Kt66 laying around I will try.
I know they may not be worth the effort but what the hell, they cann't be worse. Can they!!
