You were lucky to be able to get resistors within 10% of the required value
 :-) In 1946 my only sources were defunct domestic receivers, difficult to
find in VQ8, and many "liberated" resistors had to be trimmned  to the
required value by filing a notch (or several) in the resistor's body. A dab
of nailpolish "borrowed" from my sister completed the job.
