For sale a 1961 Western Electric Model 500 telephone that I have made into a low-impedance dynamic microphone. Original 1961 microphone element is in good working condition and has been wired to input into an audio mixing board. 15 foot balanced 1/4" TRS to XLR cable included with sale. Wired with a Shure SM57 SM58 transformer so output is low impedance and has good signal strength. Can provide audio file to hear tone and output. Have it wired so that the microphone is off when the receiver is placed on body and when disengaged from body the microphone turns on. Has original bells still intact so if you felt really ambitious you can figure out a way to send power to the ringer system to operate it. Or you could pull them off and use them as percussion symbols.
