Hi firstly can I just say Im more a singer than a mathmatision so dont understand all the theory so please forgive me... but I know what I like the sound of & Im just trying to build my perfect mic I have almost come to the conclusion that its gonna be a tube mic nothing solid state has come close to sounding better YET..... also come to the conclusion that capsule is to me about 95% the sound of a mic tho am intrigued & willing to experiment to find different flavours, I have 4 capsules to play with favorite is Violet Vin67 closely followed by the great Tim Cambell CT12 then a Oktava 219/319 then a Lomo k47 type... so far the capsule always wins
It worries me as I see soooo many different circuits being made lately & people going to great lengths to try n find a certain tube to match an old obsolete tube but then they stick in a cheaply made capsule that in my case dont know if it even sounds close to the classic capsule it claims to sound like (for $90) .....tho it is fun to try the circuits are we chasing our tails....Im not having go I just wanna spend my money in the right place if u know what I mean
Im wondering if I can make a mic that makes say my least or 2nd to least fav capsule sound as good as my best capsule and so on.....so far I havent messed with de emphasis circuits ( dont have right capsule yet)
So on to the question about the cathode bias .....I have often read on the net that electroytic caps & other caps are bad things to have in audio ? is that so, I see some mics avoid them, been reading about using diodes or LEDs to set the cathode bias ? am I talkin crap (dont answer that) did I read about using a infa red LED ? did I also read you could just use another PSU to send a small varable cathode voltage to tune a mic ?
I see some circuit use a cap just before the grid ...... so the cap effects the sound..... Is the cap less design better ......
