Mac, any chance this new receiver is a Racal? Both my 6790 and 6793A have an abundance of audio drive level. If the AF gain pot wiper has (even) the slightest contact resistance, the pot ceases to act as a divider and becomes a rheostat at audio frequencies. In that case, here will always be some signal leaking through to the audio power amp. Even if it's not a Racal, my fix may work for you, anyhow. I just added a trim pot (20K) in tandem with the AF Gain control.
See the info here:
Good Signals to all,Bob, N1KPR

I have a new to me Prem RX I like a lot,? BUT it has one issue,? even at
min Volume the AF output is very loud, too loud to be comfortable
background sound, this condition is the same no matter the the Gain
rather it's AGC or Manual setting. I checked with one other owner here
who has the same receiver and he reports the same conditions.? right now
I'm considering a pad of some sorts where it serves as an audio level
attenuator, but i haven't solved how to make it near or as seamless as I
can w/o just being a total outboard device, but in the end Ill take what
i can get..
Best regards:? mac/mc
