Behold: The Tung Sol KT-120

[Destructobot]

New Sensor now announces the Tung-Sol KT120, which has a plate dissipation of 60 watts, making it the most powerful tube in the 6550/KT88/KT90 family. A pair of these tubes in push-pull configuration can deliver power levels of 150 or more watts. When used at the parameters found in existing 6550/KT88/KT90 circuits, the Tung-Sol KT120 is impervious to overload, delivering peak power with extreme reliability and long tube life. However, taking advantage of the higher current handling capacity of these tubes, a very unique and super powerful and stable amp can be designed using the Tung-Sol KT-120.

150w from two power tubes? Yes please.

somehow or another, i don't think this is going to be applicable to svt's, but if it is, it might be pretty cool to have a 450w svt. not that i ever use anywhere close to its 300 clean watts now.

AFAIU, you can use this tubes in SVT, but there will be same 300 W
just tubes last longer.

To gain more power plate voltage should be higher. and + new output tranny, and more powerful power tranny

The idea of a 4 tube SVT is more exciting to me than a 450w svt with 6 tubes

Mike Matthews of New Sensor has just announced that New Sensor will be carrying the new Tung-Sol KT120 output tube. These new tubes are plug compatible with KT88 and 6550 tubes and may be used in any application that uses KT88 or 6550 tubes. As I write this these tubes are not as yet officially on the New Sensor web site. Look for a retail price of about $50 - $65 per tube or maybe even a little more.

wow, i can buy nos 6146b's or w's for my svt for about $22 each. so i doubt i'll be "upgrading" my svt any time soon

[Destructobot]

One of my friends who knows his stuff about tube amps (built a 2xKT88 110w amp of his own design, among other things) said that they are NOT direct replacements for KT-88, 6550, etc. I think one of the problems is that they draw quite a bit more heater current and could overheat the power xformer.

Wow, that IS handy! Too bad there's only like 16 SVTs out there that use those.

is this another el-136 with an octal base? shuguang have already made a valve very similar to this one.

Interesting..... I wonder just what "impervious to overload" entitles in real, hard, scientific data... not marketing slang/BS that makes people come in droves....

not liking those grid curves either

With one glance quick glance at them, i'll have to agree.

BUT... i dont get what this tubes real Market "BUY ME!!!" factor is.

So, what? Is it going to sound better? Revolutionize the Field of Bass Tube amplification? I think not.

.... although it WOULD be interesting to see an amp designed around it.

lol! i know of 4 on here. eventually they'll all have to be switched over, but there are plenty of 6146's still available, so i'm sticking with them.

[Volume4]

I would recommend extreme caution using these.

That said, New Sensor is doing some good things lately.

I've owned a few tube amps in my life...only 2 for bass though. And it's my very humble opinion that the reissue Tung-Sol 12AX7 may be the best sounding preamp tube I've ever tried and that includes NOS Mullards,GE, RCA, Brimar, and many newer ones including JJ and Sovtek.

Do some googling and you'll find a lot of positive reviews on the new Tung Sols, not just the 12AX7.

I may get flamed for saying this but JJ and the new Tung Sol line have put a hurt on the NOS market and for good reason.

[tomas_almeida]

Very interesting. Definetly subscribed.

[Sartori]

Hmmm. The first thing I thought of was a fantasy of Mesa putting out an amp with 6 of these in the power section.

The second thing I thought of was picturing an Ashdown 427 with these in place of the KT88's.

...for those that missed this post and are thinking slapping a set in a 6550/KT88 based amp and expecting more volume.

It might be interesting to design an amp around a pair of these instead of six EL34.

Hi.

Interesting in a tube-geek point of view, but no practical use IMHO.

Anyone remember KT90?
Anyone use KT90?

If (and as) the tube can not be used in existing amps with its full potential, and the new sensor (to me anyway) is what it is, I personally would not be too exited.

If more power with fewer tubes is the goal, the world is filled with transmitter tubes capable of plenty of it .

I want Reeves to build a Custom 225 variation with 4 of these, or, heck, go for the whole 6 if possible. Just big. And completely unnecessary.
