Sidssp makes a valid and important point, and I would argue further that the "sound" of a tube is confined what the specific tube IN A SPECIFIC CIRCUIT (Topology, Transformer, Driver stage, coupling etc.) can/will deliver. The second point - to reiterate - is the 811 (and 805, 845, 300b, 2A3) is (are) triodes - that is they have three elements, Anode(Plate), Cathode(For many triodes, the cathode and filament are the same, or called: 'Direct Heated') and screen or grid. the 6L6 is a 'Beam Power Amplifier'-per the RCA manual - and is actually a tetrode, or four element tube with 2 screen/grids and an extension from the cathode to focus the beam. They are not the same beasts....
Amps Using the 211 Tube
All things being equal (built quality, part quality, good design, etc) will a SE amp using the 211 tube sound better (I know it is subjective) than SE amps using other more typical tubes such as 6L6, etc? I want to know if there is something special about an amp using the 211 tube as far as sound quality.
Thank you
