orange amplifier th30 volume issue

[davebolden44]

hello, new here and my first post is a question. would anyone here happen to have any experience with orange amps. specifically the th30. my clean channel volume seems to be slowly falling to a wisper. I replaced the preamp tube and am 99 percent sure it isn't that. any ideas?

If the preamp tube sockets are mouted on a circuit board its likly that a solder connection has gone bad due to heat up and cool down sessions.
If this is the case you will see a full or partial ring around the tubes sockets pin in the circuit board trace.
use only a leaded type solder to fix this other was you will be doing it again if you use the normal low lead type that the amp was made with.
If its not a solder connection than it could be a something with the channel switching, like a miniature relay, or a bug type switcher.
