Believe the issue was that installing the 500 or 250hz filters also
enabled an additional amp which degraded performance. That is why
the InRad 600hz filter was installed in the 1000hz slot. I know that
I had a spare 250hz filter and tried it in the appropriate slot. I
couldn't find a situation where it improved performance over the
600hz filter in the 1khz slot.

I remember a thread a long time ago that recommended not using the

about the narrow

issue related
to the TT 500hz filter slot in the Orion1 and if it might be fixed
by using
the 600hz Inrad in the 1khz slot.
Anyone remember what that was all about?
