Hammond L102 Organ Repair Journal
by Chad Hauris, Retro Electronics and Audio Lab, Midland, TX. 8/18/06

This Hammond L-102 had a problem of hum and weak audio plus bad wiring in the power cord. We installed new capacitors in the power supply/amp chassis and cleaned all the tube socket contacs. A new power cord, plug and fuse were installed. Please click the photos for larger views.
