This is another fine mess that @mhardy6647 has gotten me into. The vintage Sylvania 6SN7W I got from Mark has become my favorite tube for the Schiit Saga - outclassed, by a narrow margin, the Shugang CV181 and Tung-Sol 6SN7. So...... 1. What other 6SN7 (or equivalent) tubes should I consider? 2. Anyone have some interesting 6SN7 (or equivalent) types they would be willing to sell? I only need one.
