What the shit?

I've gotta know how these sound. Anybody have experience? This is amazing.

In a few months they're supposed to be releasing a 6L6 power tube as well.

This is not the first time this has been tried. The claims have always fallen well short of reality. I daresay this is just more of the same bs.

Mosfets do, AFAIK, distort similarly to tubes so I wouldnt be surprised if a random person in blind test could not tell the difference. Hell, some people find it hard to tell the difference between real tubes.

I do not like complete reliance of blind A/B tests though. Even if you could tell there is a difference without visual feedback you start to second guess yourself and subtleties are all lost because you become nervous and you cant say which one is which. Or maybe thats just me.

Sound difference under what conditions? In a hifi maybe? Was it in an old blues amp played on the edge of breakup? Somehow I doubt that.


Buy one and try it out, man. Unless they are stoopid expensive. You can always take 'em out. They're not going to break anything. They may be a good thing as a spare in the gig tool box. They're probably less fragile.
Any idea on price? I wouldn't expect great things from them but if they're cheap enough

From what I remember they are like $30 USD each when I saw them in a store. But it was the jet City version not AMT.

I can get 3 new JJ ecc83 for that

$40 each. I've seen people pay less for NOS tubes.

i was gonna try out the jet city ones, but damn that price(3 for $99). Im better off buying 6-7 real tubes and not have to worry about running out of tubes for 1 amp for a decade or 2. these solid state ones supposedly sound the same as real tubes but last "forever". the difference is probably with Jet Citys retrovalves which come in 3 different gain versions.

if you buy one or 2, itd be awesome if you show some clips comparisons.

Preamp tubes aren't anywhere near expensive enough to warrant this, and preamp tubes are the ones that are fun to change anyway.

Cook up some cheap power tube alternative and we'll talk.

Yes, that's what I want, to spend more money to make my tube amp into a transistor driven amp

As Cath said it wouldn't be bad to keep them around for spares, but at the price I'll just buy more spares preamp tubes. If they came up with something that digitally modeled the characteristics of a single preamp tube, I could be interested, but if I wanted a transistor based preamp I could find that elsewhere.
I'm just a kickin' and a gougin' in the mud and the blood and the beer.

I think they would be nice as back ups for gigs. Since they theoretically last forever, you could always have them on hand in case something breaks.

If I had one, I would try putting it into the PI or something just to see how it acts. If you have $30 burning a whole in your pocket, buy one? Kinda gimmicky though.

I think AMT did/do a 6l6replacement.

Nothing lasts forever, theoretically or otherwise, as the SS amps I've repaired will attest. Power transistors do fail, they may last longer than tubes but I've had to replace more than a few in my time.

Well; at least the 6L6 versions look cool:



How they will sound (or how well they will function) is another matter. Time will tell.

i wonder if they glow. the glow of the 12ax7 retrovalves looks really cool. if these AMT "tubes" are similar to Jet Citys, then they have a little transformer and transistor amplifier circuit inside. Im not all too confident that these 6l6 tubes will last with a 25W transistor(MOSFET?) inside as well as all the other mojo going on in there even with the heatsink design. as said, time will tell.
