I've seen some threads on this topic but have not had any luck finding them. Could be a problem between the keyboard and chair. I've an outdoor gig tomorrow and it dawned on me that I should have a backup set of output tubes of the Maz Sr. So ordering them online won't do this time. I went to GC and they had #4 or #7. I picked the #7 as it was closest to the recommended #6.
Is the difference between a #6 and #7 rating that noticeable? Has anyone tried the #4 on the Maz Sr?

I've been wondering about this as well. If the rating is a scale of 1-10, does the number reflect when the amp will break up?
What I mean is, at a 7 rating, will there be break-up at 7 on the volume knob? I know this depends on other things like guitar, PU's, and preamp tubes, and the amp itself. But, I have 7's in my Mazerati now and the amp starts to break up about 1/2 way, 5. So, I don't know if my idea is correct or not. Will a rating of 2 just make the amp break up too early? And what would it sound like cranked?
Similarly, the Mazerati can do mismatched sets of el84's, so would a pair of 7's and a pair of 2's work together at all. Would it be both clean and gritty or just somewhere in between? Thanks in advance

The higher the number the less breakup or harshness. There probably isn't much difference between a 6 or a 7, but Myles would be the best one to answer this question since he works for Groove Tubes.
You might want to post this same question in the "Aske the Experts" under Ask Myles.

The # on the tube is a relative to how long the tube will stay cleanish or retain its headroom as you turn up the amp. It does not relate to the position of the volume knob on the amp. One amp or another will differ in where they begin to break up due to other design factors in the circuit as well as the tube characteristics, so the #'s could just as well be a,b,c,d,e,f, etc. Someone desiring more headroom, and or a firmer "feel" (ie. less compression) would select a higher # tube. The difference betwween two #'s, say 5 and 6, is fairly small, and from what i recall from myles and others is that it is more of a range, so youll see sometimes recomendations for a 5 or 6, 3 or 4 etc. Just know that if you want early breakup, and a softer feel, go with a lower #, like 3 or 4. If you need high volume clean, and little compression until your volume is close to maxed, go with maybe a 7- 8. I have no experience with the #'s at the extreme ends. best of success!

Thank you Myles, that helps a lot.
What about the mismatched ability of the Mazerati, what will two different pairs yield? Will it just be the average between the two or will there be some "new" aspects of tone? Thanks

Thanks In the Mazerati and Rx they are not averaged at all ... they have their own bias supply and will operate as individual properly matched duets and this can be a very cool tonal aspect. Something akin to the reason that folks use speakers that are not quite the same such as a V30 and H30 in the same cab etc. It is a cool aspect of these amps but has another great side benefit ... it is easier to find matched duets then it is to find matched quads!

Thanks Myles, I was wanting some more grit from the rati, and a pair of mismatched tubes might be the ticket for me.
