It seems I'm on a mission to try a 45 tube in my Paramount's. That of course begs the question, what 45 is recommended? I'm also going to convert my EF3 to some New Tung-Sol 6SN7GT's (available at Tube depot) and my Paramount's to 2A3. From there checking out a 45 should be easy. Just wanted to get some suggestions on what brand 45 to pursue.
