[size=medium]Yes the 7F7 with the round plates are the ones that I am using and with heavy gettering down on most of the glass. The ones I have are labeled Philco(Sylvania?) make. I also have a full box of 7N7 NOS tubes previously that I was able to acquire at a cheap price that I have not tried all of them yet. Maybe late next year. I just enjoy the MA and AIX recordings. The Aix records are very unique in sound and options on Blu-Ray. The Aix 3D video recordings are some of the best examples of natural 3D presentations I ever seen, far better that the Sony 3D recording of Lang Lang as an example. Good natural 3D video recordings require different methods from 2D video and you do not want to over blow the effect. [/size]
