RE: EML solid Plate 45 vs. EML mesh Plate 45 .........better for SET ?

Hi Pat,

Not sure why filament bias would do this - I have not looked into it.

Removing the cathode R bypass cap allows cathode-current feedback, which decreases gain, increases plate impedance... and decreases distortion. Some of the improvement you are hearing could be due to the reduced distortion.

A different capacitor could help (via a different mechanism) tune the sound to your liking. I have noticed differences between Mundorf's M-Cap and Evo Oil capacitors of the same value. My girlfriend noticed it too without being aware I had made the change to the system. Mundorf capacitors are not for me, me thinks. I will be using a Clarity MR in the cathode of my next build.

Cheers,
91.
