1st off thanks. i knew the pre amp tubes didn't have to be matched. just so i have it right tho, tap the pre amp tubes with the wood side of the pencil w/ full power on & stand by off, correct?!?
thanks you so much guys!!!
i definitely thought it could be the tubes, but i have just never actually heard an amp make that sound. what would happen if i replace a single tube, won't it be unmatched?!?
thanks so much for your help!
i have a 97 mesa dual rec 2 channel. tonite it started "whistling", only stopping when the stand by is on. when i changed the rectifier setting from diode to tubes, it reduces the sound significantly but it is still slightly there. it's almost like a kettle whistle but not quite as high pitched...
ive never been SUPER picky about tubes before, but now that i own a 2 channel dual rec, i want it to sound as good as possible. right now i have mesa EL34's & it's not heavy enuf for me. it's just not grabbing me. but the tubes could be a year more, who knows.
that said i like the tone a lot...
get off the high horse. i was using ge 6L6's that were matched pairs, & it ended up sounding great. and it's not disrespect toward my gear if it was an honest mistake.
great idea. i appeciate the suggestion. how much does a bias meter run?!? im gonna assume it can be purchased at most decent electronics stores, such as radioshack.
thanks.
what are the effects on the amp when this happens?!? i had 6L6's & somehow i THINK i failed to have it on the right bias setting. what does that do to your amp?!?
thanks
so is there a great transformer for about 250 or so that i could put in my dual rec?!? i like a really heavy sound. i love Kurt Ballou's tone from Converge. as well as Nate Newton's from Doom Riders.
any ideas how to get a nice thick distortion in that realm?!?
