The schematic of the SP-1 is the same as the mxl 603s with an exception.
In front of the 2n5401 transistors there has been added a cap (I forget the value and I'm at work, schemo at home) to shunt the highs to ground. Since no caps works for other mic's I figure I'm safe taking them out, but this is my first forray into mic's so I ask: aside from oscillations, is there a down side (assuming I want the added bandwidth)?
What do the diodes bridging the output do except provide severe clipping if the value exceeds +/- 0.7 V? Again, I'm new to mic's but I don't like diode clipping in guitar amps.
When doing the 1/2Pi RC calculation to reckon the effect of the .022uf caps shunting the out put, should I use the 150 ohm impedance the mic, or 600 ohms, or what? Any way I look at it, they seem like big caps to work against, if you want bandwidth. I notice Nueman uses smaller caps. Any comments?
Thanks
