[ARC5] HS-33 parts

[Richard Knoppow]

    For attaching tinsel wire try wrapping fine copper wire 
around the end and soldering it. Strip the ends down to the 
individual wires as much as possible then wrap and solder. The 
wire I use are strands from zip cord. Usually, the spuds (not 
quite the right word) on the ends of the leads are crimped. They 
have teeth to penetrate the outer insulation and contact the 
wire. You can reuse them by cleaning out whatever is in them with 
a drill (work by hand) and then inserting the wrapped lead and 
soldering. Usually the solder won't take the tinsel cord itself.
    There are at least two sizes of these spuds. They vary in 
diameter. The smaller ones are too small to be gripped by the set 
screws in some headphones and the larger ones won't go into the 
smaller holes.  I have seen both sizes used on ANBH-1A phones. 
This can also be a problem with Trimm Featherweight and 
Commercial phones.
     I don't know of a source for new tinsel lanyards for 
headphones. If anyone does there must be many thousands of 
headphones using Y cords or lanyards that need new cords.
