    I have an APPJ PA1502A tube amp that I just received. The volume knob on the front only changes the volume on the right channel; the left remains at full volume no matter what, whether Hi or Lo gain setting. Switched the tubes, checked the cables, and the always-on channel didn't switch sides. Any idea what this is about?

    It could be a volume potentiometer problem.

    Yeah; that's what I'm thinking. Pot not wired to both channels somehow. Silly solder.
