Last gasp ant trying to rescue a 1700 that does nothing but hum. I have it partially assembled (cartridge removed ) to test continuity and I get good signal at the cartridge head on left hot and Earth (as the manual refers)only. Other three I get nothing. I carefully desoldered/resoldered the others but still no signal. The tiny wires all seem good as the disappear into the tone arm. I assume something is broken or shorted in the arm tube. Is there an easy way to inspect the cables I can’t readily see or will I be taking the arm and wires loose to find a solution?
the tone arm looks like something I could easy destroy in the process? Are those hair thin wires replaceable even?
thanks.
