Normand,

Looking at the tube task chart for the Mark IVB, I would not recommend using the RFT in any position except V1 and (maybe) V5. Are you using the same speakers at band practice as you are at home?

 

[normandk7]

Hi,
Presently, i use a long head and a thiele with evm with the band and at home, i use a combo with evm.
I'm looking for a classic rock sound with a solo sound with mellow highs.
I also looking for tight lows...
I'd had a good overall sound with my stock boogies in my head (it's brand new) but the russian 2 tubes had broken one after another so now, i'm trying to find a better mixture.
It's bizarre that 4 new mesa tubes broke in 3 weeks...hope nothing's wrong with the amp!!!! the glass that surounding the tube broke for two tubes !!!!!I own a mark 4 for 15 years and never seen nothing like it.... but the others that are not russian 2 all are ok and works well.
And the power section are 4 yellow str 440 from mesa.
?????

I'm using 4 STR440 tubes in the yellow grade too. I've had them in the amp about 6 months. Them and the Winged C 6L6's are the ones that people rave about here. They are Chinese tubes and they can take alot of power. I've had my DR cranked all the way a few times. It's my ears that took most of the punishment not the tubes. Now I play with earplugs at high volumes.

So, I bought 5 SPAX7's to redo my preamp. Big Mistake. Talk about walking through mud. My vintage channel sounded like someone had taken a poo in it. So I popped my 2 electro harmonix 12ax7's back in V2 and V3, and it got better, but now I have too much ******* fizz. Then I found this forum, which lead me to tube monger.

I just ordered 2 RTF 1970's 12ax7 Halo getters. Where should I put them? I am asking because there is a crazy warning about cracking them if they are put in too hard, and being that these puppies cost a bit more than a spax 7, I don't want to move them around too much.

I am pretty excited though! When I first bought my boogie, it sounded so incredible! I am hoping these RTF's will open another side to this demon of an amp!

 

[normandk7]

Hey,
I bought 2 rtf at tube monger and people on the board recommand to put them on v1 and/or v5.
In one of my mark 4, i have doug's tube kit and a rtf on v1.
On my head, i have 5 mesa russian 2 and it sounds ok like that.
Good luck!!!
Normand.

 

[InsomniaClown]

Thanks man! I really hope that these tubes give me something to work with. Up until, well, 3 days ago, I really had no idea how extensive this stuff is. In fact, I wish I had found this forum before I an out and bought tubes.

I have to admit, when I first got my mesa, it sounded amazing! The stock tubes were great, but after I had to swap a couple, I noticed a change in the sound.

I also did a little gentle EQing after my post. The fizzy sound is gone, and my high gain channels really came alive! Clean channel is still a little dead, but I am hoping thats where the RTF comes into play.

I also just got notified that my order has been shipped. Sweet.

 

[normandk7]

2 months ago when i received my long head, the sound was incredible with the stock mesa 12 ax7 russian2.
I had to swap one or two (the tubes broke down after only a few hours!!!!) and i never really found that sound that i had when the amp was new....I think that mesa keeps the better ones for their new amps.
So, good luck and dont forget to tell me if you find out that sound again.
Normand.

They finally came! My RFT's arrived intact. I popped one in my amp and fired it up. The first thing I noticed was my clean channel was ridiculous. There was so much more body in the tone. It was a beautiful sound. I had it set in "pushed" mode, and the crunch was much smoother than it had been before. I am used to having the pushed being fairly ratty. Being that I play mostly metal though, I had to click on the modern channel. Here things got a little different. The bass response was a little fatter and more prominent. I'd say more about it, but about 10 seconds later UPS showed up with my winged C's and tungsol 12ax7 tubes. I guess I'll be having even more fun than I thought. My first impression of the RFT was good for cleans, but I am unsure about the distortion channel. We shall see what happens with these new tubes.

Tube rolling is addicting and fun. So is rolling speakers. 8)

 

[InsomniaClown]

I can't believe it! I popped in my RFT into V1, and then my other set of tubes arrived from the tube store. So I popped those in. V1 RFT, V2 JJ, V3 Tung sol reissue, V4 electro harmonix, V5 stock boogie (all 12AX7's), with 2 SED =C= 6L6's. Tone? Killer! I had that sound that makes just sit there and play play play. That sound that makes you play differently, and makes you more experimental in your technique. That sound that makes you hear the flaws in your playing, and forces you to correct them. My amp has never been so sensitive to pick attack and dynamics.

However, I turned off my amp for awhile, came back to it, and this wonderful little gem of a NOS RFT was blown already!!!! I have no idea what happened. I am used to pre amp tubes shattering, and the tops turning white, but this was not the case. It just didn't work anymore. There was some whooshing sounds, a wierd sine wave, and low output on all of my channels.

Anyways, I put the tung sol in V1, the JJ back in 3, and another EH in V2. I actually like it as well. I have one more RFT, and I think I'll throw that in V5 to try it out. Is there some special procedure for powering up or powering down NOS tubes?

 

[normandk7]

I do not think there is some special things to know or to do with nos tubes.
However, be sure that you amp is off before doing any change...I'm sure it's better that way.
I have a couple of rft and a try them everywhere without having any problem at all.
But i had a lots of problems with mesa russian2. It seems better now cause i do not have to change any russian2 in 3 month!!!!!!
rft sounds ok in v1 but it was not a big thing for me in v5....
It may be different for you.
Good luck,
Normand.

Well its been a long time since I have posted here. I have really been running all of my new tubes through the ringer. Clean tone, high gain filth and everything in between. all kinds of pre amp tubes and a new set of SED winged C 6L6's to try. After all of that tube rolling, my current set up is....

Stock Mesa Tubes.

Surprised? Well, I wasn't. I fell in love (plutonic love) with a tone, and now my tone is back again.

Normandk7, I didn't get around to trying my other rft in v5, too afraid of blowing it up! I did a retube with all brand spankin' new Mesa tubes, got me my sound back, even if it is a little noisy.

Are you talking about the new 12ax7 from JJ (rename by mesa) or the famous russian 2 ????
I can tell you that i like very much the russian 2 but it keep blowing out in my amps....
I did not have the chance to try the new jj (mesa) but i will as soon as i find some....and hope it will be more reliable for me.
For now, i'm with "Doug's tube kit" with a rft in v1. I think it sounds ok...

I am talking about the russian 2. It's wierd that you blow them up. I think I have blown up maybe 1 in the 2 years I have owned the amp. I looked into those dougs tube kits as well. I am still pretty tempted to try that, as well as trying a re tube kit from eurotubes. For now though, I am happy.
