The Joule Electra like other preamplifiers uses the Russian Super tube. I was not a fan of this preamplifier. Thought it sounded small and not as transparent as I had hoped for.
Check out the deHavilland Ultra Verve. Less money and sounds better. Uses a couple of 6sn7's. Big tubes big sound. I think it is true that larger tubes do have a bigger sound. 845's 300B's. Not a fan of the 6C33.
