Hi Fred and thank you for responding to this topic. This is a direct drive and looks like it is running very smooth. The speaker movement doesn’t produce any sound, the cartridge is not the best(AT13Ea), it is old, but is sounds ok, however, I will need one better soon(I have to decide which one).
I didn’t want to do it, but I order a FMOD Crossover(30Hz High pass Filter) and use it as a subsonic filter to get rid of the unwanted low frequency. Because this TT don’t have a pre-amp I had to use one of my receivers as a pre-amp in order to use the FMOD. After that it got rid of 80% of the rumble. I wasn’t completely happy and I decided to run the signal through an equalizer, only after that it got rid of almost all of it, at least 98%. I have to still close the plastic cover, if not it will produce some hum.
I will lubricate the bearing if I can and get a new cartridge, but for now I am happy with the result. Thanks Again
