The Omni Six (Six +) receive mod can be accomplished by making the following
changes to the IF/AF Amp Board:
1) Replace C3 & C29 with 0.01 uF film capacitors (>50 VDC).
2) Replace R38 with a 680K-ohm resistor.
Depending on the vintage of your Omni Six, these components may be
surface-mount types (SMD). Mouser is a great source for these components:

To take full advantage of this mod, the 2.4 kHz filters in both IF slots
should be changed to the INRAD 2.8 kHz series.

Subject: [TenTec] INRAD 2.8's and RX Mod?
>
> Hello, all!
>
> I've saved enough to purchase a pair of INRAD 2.8 SSB filters, but I'm
> mulling it over and am looking for some feedback.
>
> The INRAD $15 RX mod has not, as I recall, received much attention here.
> Someone was going to post results but I don't think I ever saw it and the
> discussion has eluded me in the archives.
>
> My understanding is that the INRAD 2.8 SSB filters improve RX audio
quality
> without sacrificing selectivity. It is also my understanding that the
INRAD
> RX mod enhances this feature, but that the RX mod is pointless without the
> INRAD filters being there to start with.
>
> Am I interpreting previous discussions correctly? Does anyone have
> feedback? I'd appreciate comments and/pr suggestions.

> Thank you, in advance, for your input!
