Tube death symptoms? Anybody?

[Quencho092]

I showed up to today's jam with my bandmaster, and after i got it warmed up, it sounded like ASS. It barely had any volume or headroom, and to be heard i had to put it up at around 7, when a few weeks back it sounded fine at 5 sparkling clean.

The bass is very farty, highs are gargly, and hardly any headroom. The tubes are about a year and a half or more because those are the ones that were in there when i bought it from this dude, they're mesa STR 6L6's, in other words, relabeled rubys?

I experienced similar problems with my peavey classic a few years back. After a pretty loud gig, it sounded gargly and farty with no headroom, and i replaced the power tubes and it was great again. Could this be the case with my bandmaster, it seems about due to die anyway, and i have NOS philips 7581A's in the mail so im just in time i guess.

if your volume and headroom have taken a poo like that, it's probably your output tubes.

Ya tubes for sure....


but on a side note my 65 Fender Deluxe had a problem with a capasitor or something else that was allowing some higher then normall voltage to the tubes and it wore the tubes out right quick....! It sounded like dung until i got that fixed!

The bass is very farty, highs are gargly, and hardly any headroom.

When you play single string lines, does it sometimes sound like two notes are coming out of the speaker at the same time; same pitch, but one clean and one distorted?

hmm, i didnt really listen that closely, all i knew was that it sounded like crap.

It did not saturate though, the notes did sound a bit semi clean, and very nasty. Again, volume was way up at around 8.

What is that double note thing a symptom of?
