I replaced the sticky Mercotac, oiled her up, and all is working fine!
215 watt, multi-channel solid state amplifier. Six speakers. Everything the more common Leslie 122 has, and much more!
We used it with our house organ - a Hammond A102. Since then I have sold it all and now have a Hammond X77GT with two X77P Leslie speakers. They have all the 715 had and more!
