Above: The BRDCSTR, a two-stage vacuum-tube microphone preamp inspired by classic 1940s broadcast audio preamps. Single-ended design with a 6SJ7 and 6J7 tubes, massive output transformer, and only one capacitor in the signal path. I have built more of these than any other design; people really seem to respond to the sound. It’s pretty much the least ‘stuff’ that you can put between a microphone and your A/D convertor. All the attitude of ancient tube studio equipment without the hum and the noise, and with much better frequency response.
