Ich weiß, dass diese Site eine große Site zum Datenaustausch ist, also habe ich mehr Informationen recherchiert, um sie mit Menschen außerhalb zu teilen.

Definitely change the preamp tubes. Every preamp tube will be different, so you should buy a selection and then "Roll" them through the preamp stages. Check out some more frequented forums on how to "roll" preamp tubes. Essentially, you just try each tube in different spots in the preamps.

Check out Tubedepot for some descriptions of how each preamp 12AX7 sounds compared to the others. You can find through that, which ones provide more gain, more bite, or smooth things out. It all depends on what sound you are looking for.

The differences most of the time will be subtle, so don't think it will be night/day differences. Preamp tubes are relatively cheap, at $10 or so for new preamps. Don't worry about NOS expensive preamp tubes for now.
