12AT7 substitutes?

Tubes Asylum

Questions about tubes and gear that glows. FAQ

My amp uses the 12at7 as input tubes. Can I use the 12au7 in its place? I know the latter has lower gain so does that just mean the tube will work but I have to turn the volume up more?

Or will the lower gain potentially damage the amp?

Thanks.
