    I have a small Champ clone that uses a 5Y3GT rectifier tube. I've noticed that it rattles, and it even sounds like the rattle is getting amplified at times.

    Is this possible?

    Also, is the tube bad? What other symptoms would a bad rectifier tube have?

    Thank you in advance for any and all help!

    Rattles are definitely possible (you're hearing it, right?).

    That tube would probably be fine in a non-combo amp. There's nothing electrically wrong with it, but it the rattle is amplified it may not be usable.

    Yes, I know the tube rattles! ;) What I meant is, is it possible that the rattle is getting amplified? I read somewhere that a rectifier tube is either good, or it won't work. There is obviously sound coming out of my amp, so based on that, the rectifier is good. Of course, the same article said that if a tube rattles, replace it.

    So ... I give. Which is it? ;)

    Thanks!

    rec tube rattles can get amplified. I've experienced this myself with (gasp) a mullard GZ34

    It's not an all or nothing situation. The same tube would probably be fine in a head rather than a combo. If the amplifier is working, the tube is working.

    The bottom line is, if it's not working for you (amplified rattle), it's not working.

    Thanks to everyone!

    I guess I'll replace the tube and be done with it.
