[Elecraft] K3 missing 6kHz filter - all ok?

[Frank Krozel]

So I purchased a used K3, it arrives in a few hours.
Trying to get smart before I unbox, I recall the past user removing the 6kHz filter and leaving in the 2.7, 500 and 250kHz filters in place.
Somewhere tonight I recall reading that all the filters need to be in descending order.  The fact that the 6kHz filter is no longer in there is leaving a “space” for it in the receivers (it has two receivers in it) is that still ok?
