    I think the tube in my 3500 is starting to short out, so I need to replace it...The question is: What type of tube does it use/which do you suggest?

    Thanks in advance! :p

    The Hartke should be using a 12ax7 also known as a ECC83. I would check with Eurotubes. He carries JJ tubes and I must say, I love the 12ax7a I got from him for my Trace Elliot head.
