Thanks for the info.. I gave in and pulled the trigger on the TU-8600, with upgraded transformers, takman resistors and mundorf SGO (pcX had a pretty good offer on it). This project is going to take a while, since I don't even have a place to put the system. (I will have to negotiate with the SO on the future of our guest bedroom Besides that, I looked into speakers a bit and was able to get my hands on a Frugal-Horn Mk3 flat-pak for Fostex FE126En which I plan to build to pair with the TU-8600. BTW, have you done any tube rolling or stuck with the Genalex from the beginning?
