I just got my board and buffers this week, and im still looking at parts to go on the board. My portable headphones are grado's, and the opamp im planning on is an ad8610 pair on a browndog (thanks Tangent!!)
im looking to get all my caps from partsconnexion, since they are canadian (like me) and have a good selection.
C1: im thinking of using a solen cap, or something similar. any thoughts on who makes the best cap for this position? i dont mind a big cap in here im probably going to mount it at the audio input. For values, im looking at a 1.0uf or 1.2uf, and a 500k resistor (i think that gives an f-3 of less then a hertz)
C2, C3: blackgate standards, 220uf/16v each... but im open to others that fit in the 10mm spots.. but i haven't seen any good ones...
C4: i have some 10uf tanalums in my box, but i'd rather use something a bit better then those if i can. are blackgate pk series fast enough to use in this position? i know, i should have gotten the wima's when i got the board... =)
