Tungsol KT120

"March 25, 2010

In September of 1950 Tung-Sol introduced the 5881, an uprated and industrial version of the 6L6GA with a 23.5 watt plate dissipation, opening the doors to the hi-fi movement of the 1950s. This rugged tube also found a home in the '59 Fender Bassman and servo amplifiers used in B-52 bombers. In 1955 Tung-Sol raised the bar of high fidelity with the introduction of the 35 watt 6550, which could deliver 100 watts with a pair in push-pull configuration. This tube was used in the Dynaco Mark III and Sunn amplifers.

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."

I think that this is interesting. Different strokes for different folks, but I think that it would be fun to do up a single ended amp using this one in the power section for guitar...class A with headroom, and a quad in a SS rectified push pull circuit could possibly make a decent bass amp. Thanks for sharing! Peace.

I was also thinking that these would be great for a bass amp. Clean headroom would be the big advantage. Would not distort soon enough for guitar, unless you need really, really loud! :shock:

What's next? A power amp with 813's? (oops, too late...just had a thread on that as well! :lol: )
