techristian Posted November 10, 2021 Author Share Posted November 10, 2021 Yep ...a Hammond Aurora. Getting rid of hum and clicking noise of Leslie. A bearing / bushing has too much play and I have decided to just disconnect the motor, for now. I tried everything to get rid of the noise but making a new bearing is beyond my ambition , AT THIS TIME. I replaced a bunch of caps on the power supply and next I am going to run some shielded wires to the speakers and make a headphone jack. There is some problem with loose connections on the EDGE of the PCB ,in the picture . I will flux it and flow some solder on the edge . I have had this organ over 20 years, but because of the noise and some non working keys I stashed it away in another room collecting dust. So now, in my quest for "vintage" sounds I am slowly reviving it . It will be sampled for MIDI and I will also be playing it "live" to recordings (with lots of editing) . In the past few weeks, I have sampled my old Lowrey Genie and my Optigan. Dan Quote TEACHMEDRUMS.COM My Music Videos RED PILL Link to comment Share on other sites More sharing options...
techristian Posted November 13, 2021 Author Share Posted November 13, 2021 So I have it back together again. Almost ALL of the problems were due to TOO MANY PLUG CONNECTIONS, poor contacts , vibrate loose. One that really bothers me is on the upper keyboard where 1/2 of the keys drop out of organ sound, when the CONNECTOR WAYYYYY DOWN at the bottom next to the volume pedal gets partly unplugged. I have cleaned it a few times. All is working now but if this was more accessible , I WILL SOLDER all of those connections instead. The biggest pain, working on this is MY KNEES. You can't put this organ up on a bench to work on so an overweight 66 year old crawling around on hands and knees ,on ceramic tile, is a sight to see, especially when he tries to stand up afterwards. But I got her done , with 2 new POTS connected to a PHONE jack. I WILL NEED TO SOLDER SOME and open up again. After I practiced on drums the connection broke again.
