Looking for some help here. I recently acquired a NEAT turntable from a member here. The tone arm is also a NEAT product. The tonearm headshell is like none I have seen before although I have run across some Garrard's that look similar. The headshell appears to be one piece with four connection points/flat plates, in the rear that mate with the balance of the arm. On the other end of the four connection points/flat plates are the connection points for the cartridge on the inside of the headshell. I have included some pictures below. I am at a loss as to how I would solder in replacement wires for a refresh. Obviously the cartridge can be removed but I am at a loss as to how one would get to the soldering points. Any thoughts appreciated and thanks for looking.
