Trying a set of KT-120 in my premier 11-A
I just got an email from Ed answering one I sent him regarding the KT-120 tubes and if they are compatible with a Premier 11-A amp.
Ed replied back that it was always drilled into him to only recommend the tubes that came originally with the amp from the factory. He said he was told that he could make an exception with the KT- 120 and he could recommend it as a replacement for the original 6550 power tube however the tube cage would not fit because of the height of the KT-120. I just ordered a quad of these to try, has anyone here used these in a 11-A ? I will give my impressions of this amp with this tube after burn in. |

Well the KT-120's arrived yesterday , installed, warmed up and biased. I set the cd on repeat and let it play on low levels for about 4 hours as I finished my workday in my home office.
My initial impressions are it has definitely helped the bottom end in fact I had to lower the sub level because it was too much bass. It seems as if the power output has increased as I can hear louder volumes at my normal volume control settings. There is a slight high end glare that I have never heard before with any 6550 or KT-88 tube that I hope will go away as the tubes age in. My overall impressions are very favorable man are these tubes big ( physical size) I am anxious to hear them at 50-100 hours. |

I took a shot of the KT-120 tung/sol compared to a 6550 Tung/sol

Jim, they are huge compared to the 6550's they have been running all day starting to sound sweet.

We need pictures of those big boys glowing!
What is the advantage of using a KT120, more output power?

Life. I really like the tung sol 6550's so these were a no brainer for me as they are the only manufacturer making the KT-120's that I know of. |
