NTD? (new tube day?...tung sol + JJecc83)

so not sure how exciting this post is but i thought i would share my thoughts on my new reissue Tung-Sol 12ax7 and the JJ I just got.

ITS AWESOME

to start - amp is a egnater tweaker 40. the tone is fairly good stock but the drive can get a bit fuzzyish when pushed. i wanted a bit more clarity and sparkle without sacrificing gain.

Current setup: V1= tung sol V2 = JJ, V3 = Sovtek

New = reissue tungsol - paid 14.95 + shipping

RESULT = wow. immediate noticable enhancement. on the cleans, not as much, but pushing the amp i am amp to about dime the gain without really any lack of clarity compared to the stock tube, which allows more gain to sound better = the amp pushed gain in a more pleasing way.

with the gain backed DOWN, it gives a nicer crunch that is crisp. slight blanket off effect.

TUBE PLACEMENT

i tried the following:

JJ in V1 / sovtek v2 / tung sol V3 (and reverse)
JJ V1 / tung sol v2 / sovtek v3 (and reverse with the v1 and v2)

conclusion is that v1 is the biggest impact. the other positions really did very little.

in regards to the JJ and tung sol, the JJ seems more rich and bold, but got a little dark with gain. power chords seems to jumble up the notes.

the Tung Sol is a bit more crisp and clear. i like it better for gain.

i rested on Tung sol V1 / JJ v2 / sovtek v3

VERDICT =

im sure in an amp with more tubes, it they make more difference but really in my amp (and most others) V1 is your critical spot. if you are going to put a NOS in, do it in V1.

jj and tung sol are good tubes. i personally find the tung sol better for gainier applications. if i was playing clean only and wanted a rich tone, i might choose the JJ.

also - sovtek 12a7wa are TOTAL GARBAGE. a piece of the tip of one chipped off while i was removing it from the amp. i barely touched the tube (still functions, just a flake off the little pointy cap). these are fizzy. 1 of my stock tubes has a rattle inside. total lack of quality control and tone.

Very cool. HNTD lol. It's good to see some actual review notes on tubes so others can use this as a reference when looking for tubes. I am thinking of getting some tubes as the ones in my Peavey Classic 30 I just bought are about 3 years old and was looking at Tung-Sol and Svetlana and few others.

I would consider the Sovtek 12AX7WA to be the shittiest tube on the planet.
I'd consider using maybe one TungSol RI in an amp if i didn't have any old Mullards handy and needed to brighten an amp up a little bit but that's about it. I'm really not a fan.

i could have bought a mullard. i really wanted a semi aggressive gain tube as to not downplay the dirty channel on my amp - i want kinda a swiss army of amps here, so if i find myself doing a harder song i want a good cutting drive tone.

i hear the mullards are mellow and creamier, and some say they are "lower" gain tubes (which i dont really understand, cause the output on 12ax7s is kinds all the same right?)

i wanted some more top end, sparkle, and bite, and everybodys comments led me to the tung sol.

other option was a JAN phillips 5751 NOS. but i am quite happy with the mullard.

yes, it was a NIGHT and DAY difference from the sovtek. me and my buddy instantly agreed, like i struck a couple of quick power chords and we just looked and each other like "wait,..yeah. yeah thats sounds different. oh yeah much better"

so again, for i think a grand total of 20 bucks and 5 minutes of no-hassle, changing a light bulb hard work, my amp is that much better.

now. i am assuming there are sovteks in v2 and 3. hmm.. tube change all around shall we?

for the record, i hear fairly good things from the egnater re-branded, ruby rebranded, shauanang whatever chinese 6l6GC tubes.

Thanks for posting this. I've been thinking about trying one myself, since I'm using all JJs and it's maybe a bit TOO dark -- considering I have a mahogany guitar too. For $15, why not, right?

Yeah, get rid of the Sovteks, they're junk. I'd run JJ ECC83S or ECC803 (if it's not a a combo) in the other places. All Tungsols will sound like a tin can - and not my tin cans.
If you buy Shuguangs make sure they are 12AX7C, if they aren't C's don't touch them.

Hey Cath what do you think of Svetlana's by chance?

That's a loaded question. The New Sensor ones that are labelled Svetlana are complete junk. The ones made in the old Svetlana factory in St Petersburg which are called SED =C= are really good.

Yeah i hear good things from winged C tubes? Right?

I would not say tin can, but my rig is already a tad dark. So i did want a brighter tube. All in all it did not drastically change the charaster of he amp too much aside from tighteing up the drive in a big way.

V2 appears to be 2nd drive stage and loop, v3 is PI.

It seems a lot of people make their pick for v1 and fill the rest with JJs. Might do that.

Yeah =C= are good.

Yeah, fill the rest up with JJ. One TungSol for V1 should be enough. The JJ's will fill out the midrange for you. Give it a bit of a Marshallesque kick in the guts.

He means old Mullards. The ones available from suppliers now are generally the new version, which isn't nearly as good.

I didn't pick that up. Yeah I meant British Mullards. Actually Aussie, Hungarian and Indian ones are good too - yes I said Indian, they were labelled BEL but were made by Mullard. A lot of Phillips are actually Mullards too. Phillips owned Mullard.
The new ones are Mullard in name only - New Sensor bought the name.

I bought one of those new Mullards just to check it out... Pretty dull tube. The best current production preamp tubes I've found are JJs.

Cool. That might be a good option for me. Why are JJ more british? Being ec88 whatever?

Tweaker emulated fender, marshall and ac tones, not sure i want to swing to hard one way. Actually, for being a 6l6 amp, it pulls off brit tones really well. Ive been rocking the brit preamp settig more than the USA.

My friend with a marshall tells me my setup actually sounds like a marshall.


Looking at reviews, it appears the most commkn good tubes are mullards and jjs, with a few randos here and there like winged c, never tried svetlana, etc etc.

You think getting the sovtek even out of he PI stage with make a difference?

He just said that the British made Mullards are better than current production... No one said anything about JJs being british.

Edit: Oh you mean the midrange bump? Dunno why... They just are.

Yes, get rid of the Sovtek. The only good Sovteks are the LPS ones. The short plate Sovteks are garbage.

Is this a combo or a head? It makes a difference.

this is a head, going into my new and beloved avatar cab with WGSs. check the sig.

i am heavily considering picking up some other tubes.

should i mix? or just go all JJ? its so temping.

i knoe v2 is either a second gain stage or just the FX loop driver, or perhaps both. v3 i believe is only a PI. I'm not sure how amps work, i know a tube can be slit 2 ways due to internal side or diode or whatever the F all that stuff is.

i would imagine i want a transparent loop that isn't too dark??? and PI? well i have all the headroom i need. I'm not sure if putting a 12at7 in there would be better? or just increase my headroom in an amp with an abundance of headroom....so, why?

I've read 12at7s handle voltage better? and this does what for me really?

Seeing as how it's a head just load up all the other positions with JJ ECC803 tubes. I wouldn't screw around with anything else unless you go NOS. The 803 isn't as dark as the 83 and they are low noise. You may find that ECC803 in every position including V1 will be perfect.

i read on eurotubes that 803s are 10% less gain. that worries me because i dont want an output drop on my FX loop, which is tube driven with the V2.

any comment on that?
