Fender Super Reverb RI rattling

[tcampos]

Hi fellows,

I've bought a brand new super reverb reissue 2 months ago.
Unfortunately it rattles like hell after a hour or so of playing. It seems that it probably suffers from a heat issue. Also in the reverb channel if I set knobs treble med and bass to 1 and the volume to 10 the amp goes dead quiet and no sound at all comes out.

Also and only happened once the amp while rattling it lost almost all volume and in 3 seconds or so it recovered.

Are you aware of issues that look like these on any amp?

Thanks,
Tiago

I(f it is brand new, it should be under warranty. I'd take it to the nearest Fender warranty repair shop and have it set right.

That's what I'm planning but the amp is behaving really strange although its tone is fantastic. I'm just curious.
I forgot to tell that this rattling appears in the 2 channels and disappears if I cut the volume all the way down...

This is normal for any BF Fender amp with a mid control. Turning all tone controls to 1 grounds out all of the audio signal. The normal channel has a resistor in place of the mid control that keeps a small amount of signal going through the tone stack.

The other problem is probably bad solder on the power tube sockets or possibly a bad power tube. Any Fender repair station should be able to fix it.

yup. The tonestack thing is typical, as stated, you can only do that when a mid control is present, the other amps have a resistor which is equal to setting your mid control and leaving it about 6 or 7. And technically if you set all controls to 0 (or 1 depending on lowest possible setting) if you get nothing that means your tonestack is working well. I have seen several where they just lose a lot of volume but there is still some coming through and that is not supposed to happen. The rattling could be lots of stuff, but its MOST likely a bad solder joint somewhere. I worked on an AC15 anniversary handwired amp, and it had some soldering joints where the chinese ladies must have put solder on the tube socket, removed the iron, and shoved the wire in, especially since a couple of the joints had insulation in them. They were SO bad. But once done it sounded pretty good.
