For sale is a used PCB 426E01 microphone preamplifier for pre-polarized microphone. It is similar to B&K 2671 preamp. It was tested with a functional microphone and a pistonphone and it works. It comes with a faulty (with some small wrinkles on the edge of the diaphragm) 377B20 microphone which failed during calibration (see picture). You can replace it with a working microphone if you want. Shipping via USPS priority mail to lower 48 states ONLY. Please use Ebay message if you have any questions. Thanks for looking.
