The resistors should be a +/- 5% tolerance.
The speaker can be from a regular telephone (mine just happened to be from
an old Autovon phone). But make sure that you remove the diode.
The Potentiometers should have a 100K Ohm range (but you may want to make
the calculations yourself to double check).
