;DProud new owner of my first Z Maz 18 2-10 combo, first let me say that this is the best sounding amp I have ever owned. When I tried it out at the store I had never felt a connection like I did with this amp. It has the best clean tones I have ever heard. I got the airbrake to go with it and really love the crunch when you come up on the vol. and master vol. Just got a bb preamp for it also. My question is will my clean tone suffer if I go from the stock EL 84 S-6 to a EL 84 S-5? I think this one of the best forums I have been on. I have learned a lot here in the last few weeks. Thanks, Tony

Depends on what you want to achieve by it. I really doubt you'll hear a big difference. I would really play around with that master volume first, it's soooooooooo effective.
Oh and...Welcome!

You would not really hear a difference between a 6 and a 5

Wait until you have to change the tubes.

Tony,
Myles is right (as always). I've got a few Dr. Z EL84 amps and have always used #6 until last week, I retubed my MAZ SR NR with #5's. They are *very* slightly "softer" (attack wise), distort *very* slightly sooner, but other than that are almost identical. If I didn't know they were 5's in a blind test I would have guessed they were 6's.
Welcome to the Forum ane the Z family!
Phil

Yea, it might feel different but probably won't sound too different.
Go with a two or a three if you want a softer feel or higher gain phase inverter if you are looking for quicker break up.

Yea, it might feel different but probaly won't sound too different. Go with a two or a three if you want a softer feel or higher gain phase inverter if you are looking for quicker break up. I wouldn't do that on a Dr. Z cathode biased EL84 amp- the cathode resistor is sized to work with a "medium range" tube on the GT testing scale- #5,6, or 7. Anything above or below this will result in the amp drawing too much or too little current (i.e. not be biased correctly). You could theoretically run a higher or lower grade tube but you would have to change the cathode resistor to match and then it wouldn't give the sound that the Doc designed it to have.

That makes sense.

I was actually trying to remember something I'd read in the forum. It's been awhile since I read it though. I believe if you get a less efficient phase inverter it will help the Maz break up a little earlier. A less efficient speaker will help too. I couldn't get the Maz to break up as much as I wanted so I traded for a 66. 'Course I had a SR not a JR.
