I recently purchased a 3047 BR44 and when I operate the Telex in analog, the coil buzzes. I have several digital engines with Telex functions and none of them buzz with the Telex function is activated. I think this is because they are using DC to energize the coil whereas in analog operation the coil is getting AC voltage. Thanks, Chuck

My guess is that the buzz probably comes from the AC sine wave where the voltage swings from positive to negative through the zero position. Regards John
