I remember powertubes used to have these color codes for small cold/warm bias variations, Red, Yellow, Green, Gray, Blue, White. I've heard that these color codes only relates to batch numbers.. http://mesaboogie.com/news/2012/03/mesa-tube-color-codes-by-randall-smith/ Today I was told my my...

Is it just me, or does the Rectifier sound better with the loop engaged (set to min. mix) and the master cracked using the Output controll to set the desired level? Sounds like the mids open up a little more then just using the Master to set level with the loop bybassed?

I'm planning to get either a Dual or Triple Rectifier. I don't plan to play either with volume above 12.00 O clock, but I heard some opinions that the Triple Rectifier has a tighter low-end then the Dual. Anyone here with any experience on this matter? I will be using this amp with EMG81...

My Recto Preamp and Recto 2:100 poweramp does NOT work like the manuls says. -The Recto Preamp manual states the modern voicing is engaged only to the Recording outputs and not the live outputs on the Recto Preamp when switching to the Red channel. -On my Recto preamp the modern mode is aplied...

Is the only difference between the Red and Orange channels on a Rectifier the voicing, or does the Red channel have more gain too?

I have a two channel Mesa Rectifier poweramp fittet with EL-34s. One of the tubes have gone gray and does lot longer light up, it's dead. So now one of the channels of the poweramp work and the other does not. So, if I continue to play through the poweramp, can it damage the channel with a...

When connecting the rectifier recording preamp correctly to the 2:100 rectifier poweramp it's suposed to sound like dual rectifier, but it does not! With the exact same settings in modern/red mode the rack setup will sound alot brighter and have less mids. I know there is a live/recording...

Does anyone know what spesific khz the bass, mid, precense (upper mid) and treble controls on a Rectifier actually targets? Alos, some say that the tone-controlls actually affect each other....is this really the case?

When comparing Recto Recording Preamp + 2:100 RectoPreamp vs. Triple/Dual Rectifier I find the rack solution to be ALOT brighter then the usual rectifer. The 2:100 Rectifier poweramp sound identical to the poweranp section in a dual/triple rectifer but It seems like the Rectifier Recording...

I've heard about a few players running their Rectifiers with 6L6 in EL34 BIAS setting cause they prefered the sound of this. Suposedly the tubes will run "hotter" or something like that. I'd really like to try this myself, but i'd like to know if it could damage the amp in anyway first. Anyone...

I di'd a little test with comparing two setups: -the red/modern channel of a Triple Rectifier. -Connecting the outputs (not the recording outputs) of a Recto Recodring Preamp into the FX return of the Triple Rectifier. The red/modern channel of the Recto Recording Preamp into the Triple...

Ok, i'm not just talking mesa now, but amps in general, could someome try to describe to me how incorrect bias adjustment will change the sound, how does it affect bottom, mid and top?

I'm allways having trouble remembering the exact settings of my controlls on my recto....does anyone know any solutin to this....perhaps some kind of stickers with 1-10 markings that fits the recto pots?

Hi guyes! When buying Mesa tubes, what is "Match Group" group actually, and what does "Code" mean. "Match Group" has a color name asigned to it and "Code" just has a number assigned to it....? Also, I was told by my vendor I had to use the same color code for my rectifier as it came with and...
