Howdy all. I don't really have much in the way of knowledge concerning KT 88 tubes. I will be replacing the ones in my 20th Shiva and wondering what are some decent ones to be had for not too much money. I saw that there are some going to around $350 / tube . That is simply too much coin for me to spend right now. What would be a recommended replacement? Gen Lion, JJs, EH, etc...?
