[ARC5] Volume control - ARA receiver

The ARA receiver (mine is the 3-6 Mc/s model) has no audio gain
control, with the level of audio being set to the pilot's preference
by the RF gain control.

I'm building an LM-380 audio board with a 600 ohm pot to terminate the
600 ohm output from the set and adjust the level into the LM-380.

My question is, should this pot be mounted somewhere accessible so I
can adjust the audio level, or should it be non-accessible and the
level set by varying the RF gain control alone? The set has the usual
ham mod with headphone jack, RF gain, and BFO on/off switch mounted in
the space that was occupied by the little pullout box.
