glad this is helpful. One thing to keep in mind is these are my opionons for the MOD50 only. Tubes and speakers "mate" with other amps and cabs in very very different ways. For example. In my Super Reverb JJ 6L6 tubes do not sound Dark at all and my tube of choice for that amp is actually Winged C 6L6GC tubes.

The other thing is the preamp tube in the v1 of each module will change tone a ton too. So it may be worth noting I am running 12Ax7 EH tubes in both spots on the B'Man and the SL2 when making the notes on the power tubes above. I generally run new production Tung Sol 12AX7 tubes in the Vox module and the T/D module and I run JJ 12AX7 tubes in the Erect.

Oh and search for my other posts you will find a line by line for the MOD50 and some speakers I tested just like the tubes :)
 
So I just ordered some of these bad boys and a bunch of other tubes but damn if I can't wait till they get here SHEEEEESH!I've got no patience :D
 
Tele,

I could not agree more with your tube assessment. :2thumbsup:

On the money.

I would only add that I liked the Mullard EL34 re-issue fro heavier distortion, real nice Marshall grunt. But they don't do clean all that well.
 
Right now I have EH 12AX7s and SED Winged C EL34s(the bias drifts on these) in my B'Man and MHG.

Any thoughts on the preamp tubes?

Thanks guys, looks like I am going to order some TungSol 5881. Any specific place to a order a matched set? I'll probably do Doug's tubes, although on his site they are said to have mostly been used in old Fenders so i am confused. Thoughts?

Thanks!

EH 12AX7 for the bassman for sure. You could try jj EC883 in the MHG (I do not haver this module) but my guess is the EH 12AX& will be best for it too.

Doug Tubes is good or Jon at the Tubestore.com is really helpful. Bottom line is from a spec sheet prespective the Tung 5881 should not be the right tube for the MOD50 but man for what every reason it is haha. Trust us you will not be disapointed.
 
Tung Sol 5881 is just ridiculous in this amp. Out of this world good.

I like EH preamp tubes in my EG5 and will probably put them in E-Rect as well. But I want to put some Shuguangs (or other chinese equivalent) in the SL2. Bogner swears by those tubes and Ill be interested in seeing what they do to the SL2.

I guess EH is also good in clean and midgain modules but i havent tried yet. I need to get whatever Sovteks I have out of here. Those tubes are just blah. Reliable, but the tone is very basic and lacking character you find in the other tubes.
 
Okay, I'll order a matched set of Tung Sol 5881s from Doug. I'll just stick with the EH tubes in the modules. What about in the amp itself? What preamp tube should I test in that or leave it?

I think i also have a tung sol 12ax7 sitting around. I had a tech tell me tung sol and EH are tons better than JJ preamp tubes.

those are all personal opinions,try them for yourself and see,when your grin gets from ear to ear,you know you're in the game.I like all the ones you've suggested except the JJs,good but not me.The chinese in my SL2 are real good for me,the EH are good and the tung sols I like too!But you got to try them for yourself..
 
Agree on the JJ pre's. Just ok by my ear, certainly not my fave. I really like the Tung Sol, Chinese and EH. The Tung Sol 5881's are tough to beat. I do like Ruby and SED EL34's though as well. I have a set of KT77's in my Eggie class build amp that just kill. I need to try them in my Mod and see how they sound. Those JJ 6v6's are really fun too. Can't wait for the M2 man........... then I can run my T/D, Vox, SL2 and EG5 :rock: :thumbsup:
 
If you get a chance to run the YJs in the MOD,it's cool!I really dig the way the EL84s sound in it.I should have thrown them in the box for you to give a try Matt :D
 
Okay, ordering the Tung Sol 5881's today from Doug's tubes. They better be a matches set! LOL!
Which ones to buy? Early, Average or Late distortion????

My current SED EL34s are DRIFTING all over the place! I can't keep em biased. Is that the sign of bad tubes???????? I ghot this amp used form another guy so they may have banged around in shipping.

Also, you guys are talking EH and Tung Sol for preamp tubes. Is that in the modules or the amp itself?
 
Just pick a good EH or Chinese for V1 of the amp. We are talking mainly about the modules. V1 in the module is the one on the left as you face it. Definitely makes a difference.

Thanks, I am not sure what is in V1 in the amp but the amp is fairly new...maybe a year at most so I am sure the preamp tubes are fine. The tubes in the modules are both EH which I was told by my tech are better than JJ but maybe not as good as tung sol.

Any idea why my power tubes bias drifts all over?????????????????????/ Bad tubes?????????
 
Yeah drift is generally bad tubes or bad power. For example if you have a tone of gear on in the same power circuit that is like rated for a bedroom you will see a drop in power to the amp and in some cases a drop in bias ofthe tubes.

I do have this plugged into a house outlet so maybe I need a power conditioner? Anyway, the only other thing I have plugged into this strip is my pedalboard. Sometimes they drift up though, not down..

It would not just be the strip and the one outlet you are plugged into. The whole room lights and all are wired to the same breaker/fuse. So for example I had my computer, printer, monitor, studio monitors, reptile lights, space heater, humidfyer (it is winter and the reptiles need it haha) and two amps on. All plugged into diff outlets around the room. Bias drops by 3-4 mA in these cases. Then raises back up.

As far as drifting up goes if it not what I described then tubes could be bad or your transformer is going bad is my guess.
 
It is weird...I can sit and watch the bias climb from 35 to 36 and up....

weird, it is only a year old and I baby the amp. I thought these used good transformers? Maybe I'll end up having to chip back to Egnater.

I have no back up. Oh well...
 
Ordered a matched set of Tung Sol 5881s last night from Doug's Tubes.

Next month I have a jam session with some guys and the one guy uses a Marshall half stack. I'll have the Egnater and Ear Candy Buzzbomb with Sugar Cone speakers so I am interested to see how I compare.

If you take the MHG be prepared!

For what? You mean because it is dark?

I might look at getting another module soon. Something versatile that is capable of rock and metal in channel A. Would this be the EG5 or the EG3/4? The SL2 interests me but it sounds like channel A may only be good for classic rock and hard rock....not heavier styles.

If I get a boost pedal for leads, then I could use both channel A and B for rhythm as well.
