Got a buzz on low notes on my new Maz 18 Jr. reverb Combo 1-12. What should I look for?

Man, rattles and buzzes can be quite frustrating.
Some things to check would be:
Are the four bolts on the top of the amp tight? Is the handle itself vibrating? (stick something under the handle to make it taunt and check) All the tube retainers seated well?
Lastly, try moving the amp into another room and playing again. You'd be surprised how sympathetic vibrations can start in window panes and pictures on walls, etc. when you hit certain frequencies. I can get an acoustic guitar that's sitting on a stand to "play along" with me when I hit certain notes.
Good luck, Eddie

Many times this is one of the output tubes being a bit physically microphonic. Have somebody play the amp at the offending frequency and using something so you do not burn your finger, lightly hold one output tube at a time to see if this is the offending culprit. You can also test the preamp tubes in this way and the rectifier.
