I bought this heathkit audio analyzer today. I have no idea what it is. I will post a pic later as my cameraman is out of town till tonight.:) I am curious about the tubes. It has five heath tubes by mullard:12AU7,12AX7,12AT7,EZ90 and one I cant tell because some of the writing is off, Ill post a pic tonight.

Thanks,
Stankmuffin
