I was jamming at a friend's house today and suddenly my amp volume just dropped. I thought it might be the power tubes, I replaced them but i still had no volume. I checked the fuse and its fine. I have not had a chance to replace the preamp tubes. Could this loss in volume be the cause of one of my preamp tubes or is it something else?

thanks in advance
could be any number of things after that. Take it to a tech as it might be part of the components. Did you replace the rectifier tube? if not, take it to a tech.
For those who care.

Well it turns out that it was my V2 tube in my preamp I replaced it and everything is fine.
congrats on the fact it wasn't something more serious
