5751s are cool being a lower gain version of a 12AX7. Now I can only guess what the 5751 would do to the Maz18Jr based on what the tube did for my 66 deluxe reverb when I switched out the 12AX7s for 5751s. I think it would give more clean headroom and a rounder top end. I was needing more headroom out of my Deluxe and Mike and KCA recommended the 5751 over a NOS 12AX7 for a preamp tube.
I love 5751's in my MAZ SR. I have them in V1, V2, and sometimes in V5. They took the edge off, are very warm, and have a beautiful high end. I have GE 5 Stars in mine. I got lucky and found a batch of 4 of them on Ebay for 50 bucks. The luck continued in that they all work, sound great, and have no problems.
That being said, Mike at KCA, or Doug at Doug's tubes, are both great to work with, and test and stand behind what they sell.

I know this may run counter to all the folks looking for NOS or boutique stuff. I too have tried all kinds of JJ's Svet's etc.
But I have found that in both my Maz 18 and Maz 38, that Groove 12ax7 R1 in V1 and V2 and Groove 12ax7C's on the back end work best. Just a really nice balance. Smooth tone with a very linear break up. I also use Groove #6's in the power section.
I mean I try all kinds of other things. I have five amps, and I am a tone nut too. Two are not Z amps. But I just keep coming back to the Groove stuff. For a gigging musician it gets me 95%-98% of what the boutique stuff gets and they are indestructible.
Bottom line is I get compliments on my tone all the time.
Just my $.02. I hope this helps.
Sometimes the silence between the notes is more important...

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!

capofirstfret: I've experienced tube rattle in two different amps that I've had. In both cases I bought the rubber rings from Eurotubes and it fixed it for me.

GuitarZ: Idiot! I wanted to put a little air on my Zoom H1's circuit board to clear out any residual Deoxit from spraying the input connector. Guess which can I picked up to spray. Yup! Not the air can.
