Hello Ratsol,
You will need to be more specific as to the brand and model of amp/preamp for others to be of help to you. This way you can get an accurate answer and know what to expect from your equipment or the equipment you are interested in.
I own BAT tubed equipment, the beauty of them besides sounding "freakin' great" is that when a output tube goes on their amps you will blow the corresponding fuse for that tube. You flip over the amp replace the fuse and if you blow the fuse again you can be pretty sure the corresponding tube is bad and needs to be replaced. It has auto bias for each tube so no need to futz around with that.
In general when smaller signal tubes start to go in amps or preamps the sound usually starts to sound dull, rolled off highs, bass is not as well defined, less dynamic, the sound becomes slow and boring. Hope this helps a little.
Good luck,
Tom
