We will be building the T-47 from microphone-parts.com! The nearest commercial equivalent is the Mojave MA-201 FET (MSRP $795). The kit has custom PCBs, a recreation of the Neumann KM84 circuit (improved and hot-rodded), and a custom transformer. The finished mic has higher output than the Mojave, and it has both a 10dB pad and cardioid/omni switch. The website price for the kit is $349 including a nice-looking unbranded microphone body.
