I've been religiously buying good ceramic caps for feedback networks and such but have often wondered about using mica caps here. What, if any, differences have you seen/heard?
true. it was just a thought that passed through my head. i was wondering if they imparted harmonics or anything of that nature but I suppose that doesn't matter in an application like this.
high quality ceramics in 22-100pf ranges are still a dime a dozen though.. as opposed to 1.60$ for ONE mica..
