Tung Sol reissue tubes suck

[microdmitry]

I bought a few on **** for one of my projects, and they're easily twice as noisy as JJs. I would not recommend them for the first tube (the closest to the input jack) in particular, and in very high gain amps for the second tube in the lead channel as well (location varies).

Buyer beware.

i was always under the impression from everything people told me in hte past that evilvay is the utter most worst place to buy tubes....people will mixmatch and restamp logos on tubes, not only that, some actually buy underrated and underpar manufactured tubes from no name places in bulk for nearly nothing
and claim they are good

i go to tubedepot.com

wich in my opinion has some of the most tubes i ever seen and they have more than they advertise some are obsurb prices, but in general it was the best prices and best equipement to classify them

i ordered tunsol 12ax7 thier high gain tested tubes and it was the best buy i ever made.....when they get underpar stock, they will literaly sell a tungsol 12ax7 for a dollar!!! and other manufactured tubes for even less

but theres no guarantee and sometimes they dont even work

but they say that, other than that, ive never had a issue and found that the tungsol tube in the preamp increses gain and headroom and is one of the noiseless tubes i have ever encountered, each and every single one i bought for any of my amps

some of the ge/rca models i have ordered for my fender bassman 67 were very quiet but after a while they got noisey, i replaced them with eh and they lasted longer and the noiseness was the same, and then went to tungsol and it was great, but the amp went toooo muddy....but for all my other gear i use of rinstance

in my preamp eh12ax7 (hg) tested in my 2120
and in my peavey power amp i use two tungsol 12ax7 (hg) tested preamp
and eh6l6gc but i specificaly ask for a pair that is rated over 9900.....
if i wanted to spend more money id get a svetlana NOS for sure, or even a c cap wich is still built to regorous standard and use premier meterials that are old stock mined and procesed in the comunist russia back in the day

I just bought a couple but I haven't tried them yet. They get excellent reviews. I wonder if you didn't get some second rate tubes from the bay?
Anyway I'll let you know how mine work out when I get around to installing them.

Dude, aside from mil spec stuff, I wouldn't trust anything made in Russia "back in the day". I grew up there. These days, you can expect quality stuff coming out of there, but back then nobody gave a sh1t. That's the communist system. Whether you do good work, bad work or no work at all the salary remains the same.

I put the JJ's back in. Eight fifty a tube, low noise - you can't go wrong with them.

[microdmitry]

Actually, maybe the noise is more apparent is because they have higher gain, so noise from the first stage gets amplified more.

Never had a problem with the 3 I've bought from a retailer. Also very popular V1 tube on sevenstring.org and HC, with lots of people having zero issues.

Sounds like you got some duds.

dude i was born in russia
my parents are both latvian orthodox, my dad was a tank engineer for the russian army, my mom was a f-ing sniper .... well great with guns lets say...years later, my dad told me to spec....back in the day, the tubes in russia were the best in the world, becasue the minerals and refining process of materials for tubes for instance were the best..nothing but the best, and if they didnt like something, they rejected it and sold it bulk elsewhere....

dude, the russians werent soo bad, they paid close attention to specifications and for tubes, old svetlanas are some of the best you can get

nah the true tunsol high gain tube is almost noiseless, ive never had noise, not because of the gain but the meterial itself, handles voltages better.....much better than regular tubes, tunsol high gain rating are some of the best non microphonic tubes you can get just becasue they handle the voltages better

[microdmitry]

Tube itself can have low noise, but resistors in the first gain stage have noise too. If the tube has much higher gain, it will amplify that noise just like it amplifies any other audio signal. Given that the gain is multiplied with each successive stage, even if each tube's gain is not that much higher, the output will be substantially noisier, which is what I believe I'm observing in my case. This is the reason why, no matter what tubes you put into a 5150 it won't be quiet. Five amplification stages. The only way to make it quieter is by installing lower gain versions of 12ax7.

The way to go.

hmmm inherently some tubes are expressive on the noise in the preamp stages....but...if you use a noise gate in sure you can solove it withut having to use a lower gain 12ax7

I run my amp with no effects most of the time, just a little spring 'verb for the "atmosphere"

[losgatosrg350dx]

you must have got bunk tubes, possibly under rated or rejected tubes, that are also sold in bulk to people like on **** who run scams

go to tubedepot dot come

and order a hg version of the tungsol, and come back to the forum at let us know
youll know your getting a quality product well tested and only at the best of quality

id love to see how this works out for you
i never buyt ubes from ****, that seems to me like such a risk dealing with those people

I've had excellent results recently with EL34s and 6V6-GTs from Electro Harmonix in my JSX, Rivera R-55 and Fender Vibro Champ.

Really appreciating my (currently up at college) tube-less setup right about now, lol.
