    Hey there, thank you in advance for any info you may be able to contribute.

    I have a 5e3 and I have replaced all tubes at this point. I have an intermittent noise like a quiet storm that can sometimes get pretty loud, but it doesn't happen often and it only happens when I am plugged in to the bright channel. If I have the volume up and plugged into the normal, I can hear it. Then it goes away when I turn the bright's volume back down.

    Wondering what could cause this kind of noise. Taken it to the shop a couple times only to be told that it is fine.... they can't find an issue.

    I can still use it, but it bothers me that I don't have reliable access to both channels.

    Any ideas? Capacitors?

    Thank you.

    Intermittent problems make me worry about cold solder joints. If it was mine, I'd pull off the back and power it up. Let it run a while, get nice and warm. Get a wooden chop stick. Put the volumes up into the middle of the range, about five or six. Put one hand in your pocket for safety, and use the chopstick to tap on every solder joint. Be systematic. If you tap on a bad joint, you will hear it. :) Don't stop with one bad one, if there's one there could be more.

    @Ricky D. is giving you great advice. Fairly safe too. Luckily it's a smaller circuit.

    Yeah then I'd be looking for a bad solder joint or tube socket connection. Like Ricky, I'd chopstick it.

    You need a new tech. Your description of the noise localizes the problem area.

    Thank you, guys. Very helpful. I've got a number and I'll give someone else a shot at it.
