Ive got a mesa dual rect roadster. I noticed one of my clean channels is kicking some distortion unless I turn it real low. I boought it used so I dont know how good the tubes are. Could this be bad tubes?
#2
Absolutely. Most likely a preamp tube, but you might as well get a full set of replacement tubes and then keep the good ones as spares.
#3
Sounds like a GOOD tube to me

Yeah, tubes can do all sorts of strange things when they start to go. Volume drops, increased gain, humming/buzzing, and the old complete short/blown fuse.

And so it goes

Doesnt the second clean channel of the Roadster have a naturally gritty vibe?

That amp has like 14 at the prices here, about 20 dollars a pop for pres and 40-50 each for power, I can buy an entire new amp with the cash

I think he meant full preamp set... but yeah the roadster and road king have lots of glass.

No, I did mean a full set. If a complete retube is too expensive, the best option is a set of power tubes and a couple preamps. You can replace the preamps individually so you don't really need a full set of those.

TS - I'm assuming you know what it should sound like... Right? It sounds like it is definitely a tube issue, and since you'll need a whole set eventually why not buy them now? Look on the bright side; it doesn't have to be biased so you'll save time and money on going to a tech.

Legend has it that the first attempts at producing distortion out of an amp without simply cranking it to full volume was done by old bluesmen using faulty or poorly seated tubes.

No.


Well, technically it could be done, but only in the same way that you could change a cat into a hamburger. It's an unpleasant process, and nobody is happy with the result.

The pierced speakers thing is normally attributed to the Kinks which happened quite some time later.
