Hello all, A friends' tape deck has problems, caused by faulty pickup leads (over time these have suffered metal fatigue). The leads are in the form of a sheathed and shielded 4 conductor cable. The cost of an original part (if I can find one) is probably excessive, and I'd like to use some other cheaper shielded cable. Questions: 1) do I have to worry about impedance matching? A friend says that the head and head-amplifier will be terminated to match each other, and the cable characteristics are negligible. Is this true? 2) how close do I have to match the cable for shielding, wire gauge, and wire alloy? I don't have the knowledge to tell if these are high silver content, or something else. 3) when soldering, should I try to use a silver solder? What temperature? How susceptible to heat stress are tape heads? If you can help, please e-mail. If there's any interest, I'll summarize. Thanks Mike Hermann hermann@cpsc.ucalgary.ca Department of Computer Science | University of Calgary | Work: (403) 220-7691 2500 - University Dr. NW | Fax: (403) 284-4707 Calgary, Alta., CANADA | Local Time: (GMT - 7) hours T2N-1N4 | -- | Mike Hermann | hermann@cpsc.ucalgary.ca _Organized_ religion is like organized crime: it preys on peoples' weaknesses, generates huge profits, and is nearly impossible to eradicate.
