SB-401 Parts AM filter question?

[Kevin Thomas]

Fred et al,

My guess is that the filter was produced in the 21st week of 1971. This is
somewhat common nomenclature on electronics parts...and other items....
Since the bible (Penson's book) says that the 303 was made from 70-76...this
kinda fits..... The regular AM filter was 3.75Kc...although I have see a few
5Kc filters for sale claiming to be Heath filters. Never seen a pic of one
of the 5Kc ones so can't say for sure... I am sure we will see other, more
qualified, responses on this......
