Preamp tube question

I'm changing the reverb tubes in the preamp section in my AC30, and suddenly discovered that it was an ECC82 in an ECC81 socket. Will this damage my amp?
 
Re: Preamp tube question

I think you should be fine. If I am correct, the ECC81 is either a 12AY7 or a 12AT7. In either case, they are all 12AX7 or (ECC83) type tubes, just with lower gain factors. I don't see any problem.
