Hello all, this is my first post, but I've been a lurker for some time. I have a question for anyone in the know. I left my tube amp on for 12 hours when I accidently left the house without turning it off, it is a DIY I bought from someone and is running 307a output and 6sn7 input. Obviously it is not suggested to leave your amp on for possible wearing out of tubes, but should there be any danger in leaving the amp on in terms of damage to the amp itself or degradation of sound. When I did get home, the amp was very hot. I want to make sure it didn't damage the circuitry.
I just want to clarify not to worry about damage.
Thanks in advance
