12AY7 worth it?
« on: April 26, 2011, 08:27:41 pm »
 I'm thinking about getting a 12AY7 to try it out, but there a little more expencive than a 12AX7 and I'm wondering if it's worth it. Seems like a 12AX7 is more bang for the buck. Now, I know there is a difference in gain between these tubes, but is there much of a difference in sound when used as V1? You get less gain from a 12AY7 but couldn't you just turn down a 12AX7. I could see how a different tube would make a big difference in a later stage, when you start pushing it around, but if it's used as the first tube isn't the guitar's signal pretty small and with small signals isn't a tube more linear? It's only when you push it that the curves really start to bunch up? That's when I'd imagine a more noticable difference between tubes would be heard.

In V1 is a 12AX7, a 12AY7 that goes to 11, or is there more of a tonal, or EQ(treb,mid,bass), difference between a 12AY7 and a 12AX7?

Never tried one so I don't know. Wadda you think? Worth the extra $$$?

If you like messing around with tubes you should have one of them aand some of these too... 5751, 12AT7, 12AU7 and even a 12DW7. Each will give an amp a new flavor.

The 12AY7 is a very musical and sweet sounding tube, IMO.  I also like the 12AV7 alot.  It's not just the gain factor, there is a tonal factor also. 

For example not all 12AX7's sound the same. Correct?

with respect, Tubenit

Thanks, I think I'll go for it. It's worth a couple extra bucks in the name of experimentation.

YES!

I've been putting them in lots of amps lately.  I originally found a pair of NOS to try first, then I tried the Electro-Harmonix ones, and I'm totally satisfied with the new production.

I have used the EH12AY7 in the V1 slot in 1/2 a dozen amps. Favourite V1 tube for blues geetar amps. EH does a pretty decent specimen for a current production tube. Worth the extra that you pay for it. (Maybe if we all bought enough of them the price would come down). I keep a couple of spare ones in my stash.

I have bunch of the tubes mentioned i cant seem to say no to the bid button.  :l2: and I have really come to love the 12 ay7 and when i want a clean bluesy type amp I have 2 in my blues miester amp v1 v2 and really love the musicality of that tube if you can call that a word, since tubnit has used one ive tried my 12 av7 in a couple of spots always ended up back to a 12ay7 for some reason. experimentation with differant tubes is a blast.
 man its late I need to go to bed I talk to much when Im tired. thank guys by

I'll second that emotion. Once you've got your amp built, you have to roll some different tubes in it. 12AY7 is my favorite preamp tube but I always try a U, X, V, T and a 5751, in each socket, before finally settling. Don't have any DWs tho....

If you ever build/buy a "Tweed" type amp, you are really going to want that AY7.

Yes, I think there -- all -- worth it!

I'm a carpenter and I have, oh, at least 10 different hammers, huh, and I'm still bend'in nails instead of sink'in them.        :laugh:                                         

Point being, different tool for different job.

I love my 22 oz. framing hammer!  :laugh:

Good example. Replace both preamp tubes in a Hot Rod deluxe with some lower gain tubes. You can set it up so the distortion channel is clean... And really tubey sounding.

I really like 12AY7 in tweed types. In AB763 it also gives greater expression, IMHO. Actually, I can say AY is my favorite tube for lowgain amps. Once I retubed a 2203 with V1 being 12AY7, since it's owner wanted the amp to be 'more bluesier'.. very nice sounding amp for blues. My own plexi+Hotswitch runs TungSol-12AY7 and I love it for a blues/crunch typ-o-rock :guitar1

Instead of a hammer I was thinking of a 12AX7 as a 3/4" adjustable wrench and a 12AY7 as a 1/2". Up until 1/2' bolts either one will do the job, but if you want to tighten a 5/8'....

 I need to do less thinking and more trying. I'll get a couple and experiment.

Thanks for the advise.

I seem to usually compare electricity w/ water analogies so I'll use this one. Think of a lawn sprinkler w/ a nice even 15 foot fan spray pattern as being a 12AX7 and the water being "the flood" of electrons carrying your signal along to the plate (grass). Now w/ a 12AY7 you have the same 15 foot distance but instead the water is coming out in a finger spray pattern. There's less electrons carrying your signal but it's still giving you plenty of "distribution uniformity" over the same area but w/ a little better control.
