BTW, Brian...
The Telefunken smoothe plates were a favorite of mine in my former EAR 834 phono stage..
I had moved on from those tubes to others in my EAR life
I chose not to respond to your search for guidance in your particular phono stage, simply because I had no experience with your Trumpet.
My feeling is, certain tubes work better, and/or are designed to work best in the original designer's design.
So, how could I recommend a tube for the Trumpet by my experience in a different design?
