Tweeters also have a resonance that affects the sound. Good damping from the (solid state) amplifier controls the tweerer so you don't hear the resonance.
i'm wondering if i could connect the screen grid directly to the (+) of
the psu and then decouple it with a 10-22uF capacitor.
P.S i decided to use DIN connectors as once used to be, but unfortunately i couldn't find speaker DIN, only the 5 pole ones! so i'm going to use them for input and for output, i'll post photos soon.
