Be Bamp with KT120 Tung-Sol tubes

A fellow builder had bought a pair of these tubes and claimed they were an improvement over KT88s and others. I had to try for myself. Just dropping in the tubes in where the JJ Blues Glass KT88s once were gave me a 2W improvement in my SE UL bread board amp raising the power to 9.7W. Bass is far more controlled and mid-range crisper and clearer. Idle current is 112mA up from 93mA and HT+ is 400V with bias at 34V. Operation is class A. These tubes are not only impressive looking but have improved the performance of the amp. +/- 3db points are 26hz to 36khz.
