The TEKTON 8.1en are 8 ohm speakers. The 8.1t are 4 ohms. 35 watts is more than enough to drive them. Your tube amp won't have a problem driving either of them. If you can use a floor stander you may want to consider the Tekton Lore. I just got a pair yesterday to go with my fully restored Scott LK72-B and they sound very good. At $850 plus shipping they are a true bargain.
