I just picked up this 9v battery supply in a minidisc collection. What has me slightly confused is this unit has two gain slider controls and is in an otterbox case.
Did the first versions of these come in a box like this? Were the slide controls added later for this as a custom job?
I bought this lot of old equipment figuring I could use this SP 9v supply as an alternative to the really simple Church Audio one I've used for a decade +
Just curious if anyone else has seen a model quite like this.

Looks like a limited production unit. I remember seeing these.
Very nice construction inside.
Good capacitors.
Switch for roll off.
The sliders all you to attenuate a bit more, if you were using a device that clips on input.
Most modern flash recorders have a wide range of input levels, but this is certainly nice to see. You can set the levels of the sliders inside to box, tape them down and not worry about it.

I have this box. Yours is newer than mine, I did not have a hinged cover (four screws on mine). Purchased in '98.
The sliders were added for recorders that had to be put in pause-mode to change levels. Mostly minidisc recorders.
This really was a great solution for level adjustment in that situation.

This! I have/had the same box as dgny. Mine had a cable output that eventually went bad, and I replaced it with the model without the sliders. (and several other batt/pre type boxes).
