I'm going to be building the a5500 tube mic kit from Aurycle soon and I've done quite a bit of research regarding possible upgrades. Swapping the tube is not an issue for me, however the alternative capsule of choice (the Peluso PK47) is almost twice the price of the kit itself! Is there any possiblity of modifying the circuit to work with one of the more popular (and much cheaper!) LD electret capsules like the TSB-2555A from transsound? The transsound capsule doesn't have a built-in jfet so it shouldn't require any modification, however I'm sure I'll have to remove the polarizing bias voltage. Beyond that, is there anything else that must be changed or should I just try it and see what happens?
