For sale is a used Bruel & Kjaer 2671  microphone preamplifier for pre-polarized microphone. It was tested with a functional microphone and a pistonphone and it works. These are the last few I have and it will be a while till next time I have some for sale.  It comes with a damaged (with wrinkles on the diaphragm) free-field 4189 microphone which still outputs signal but cannot be calibrated. This microphone is included in the sale but only considered it as non-functional parts. You can replace it with a working microphone if you like. Item also comes with a box and cal sheets (see picture) but the cal sheet's microphone serial number does not match the one on the microphone. Shipping via USPS priority mail to lower 48 states. Please use Ebay message if you have any questions. Thanks for looking.
