MODEM NOTES

     I've received several requests for alternative part numbers for the
replacement cap, resistor and mosfet.  The cap can be a garden
variety ceramic, the resistor can be a 5 percent 1/4 w, and the mosfet can
be either the originally specified VN10KM (available in places from RS) or
an IRFDZ13 mosfet, which is RS part number 276-2073, and which
should be in stock everywhere.

     Again, I'd like people to let me know how this modification
works out when they've put it in.  Thanks
