Below is a table containing
the 19 Set resistors, their marked values and resistance readings
made with a digital resistance meter
You'll see that not all the
WS19 resistors are included as some were not readily accessible
and a few were shunted so the results were meaningless.
Mostly the resistors are of
US design and manufacture but a few (470Kohm) looked British.
The US made sets have a number of different resistor values to
other sets; in the area dealing with the test meter and in place
of some instances where the original design used paralled parts
such as two 47Kohm replaced by a single 22Kohm plus, in a few
instances, specific resistors are not fitted in the US sets.
