For sale is a collection of vacuum tubes I put together years ago from well respected vendors after soldering together a Decware ZKIT-1 in order to hear the differences between these highly recommended valves. In this offering you will find some hard to find and very well regarded specimens. All have been tested on my customized Heath TT-1 with digital plate current meter to be at or exceeding manufacturer’s specifications. None were utilized for very long as I purchased others of the same when I found those I liked best.  I kept these “new” as control samples. They are as follows:
