DIY Audio Projects Forum • Coupling capacitor
I dunno, coupling capacitor selection is pretty subjective isn''t it?.. Your LF rolloff is set based on the RC network not just that coupling cap.. So if your grid leak resistor in the next stage is really high, then you don''t need as large a coupling capacitor at that point in the amp.. If it''s a really small grid leak resistor in the next
