I'm trying to convert an MXL 603s circuit, which has a non-electret capsule, to an electret version. I'm pretty certain that the only real difference between the two would be the fact that the non-electret capsule needs a polarizing voltage, whereas the electret is already polarized. You can find the schematic for the 603s here.
I'm pretty sure what would need to be removed is the section of the circuit starting from the connection to the capsule, then moving counter-clockwise until you hit R10 (1.5k). I think all of the components in that entire section are for polarizing the capsule properly (although I definitely don't understand the purpose of the 2N5551 transistor and the inductors).
If someone could tell me:
Am I correct in thinking that those components are for polarizing voltage, and can be removed?
How would I need to change the preamplifier components (the ones that will stay) so that they will work with an electret capsule that has an internal FET? This is the capsule I'll use.
