Hi Frank,

The Ultra 550 audio boards has an empty space for another filter cap, is it reserved for future upgrade, or is it used for the double-die transistors option?

The boards are pinned out for a variety of capacitor combinations to make the value and voltage we require.  Depending upon which capacitors we are using this location could be populated with between two to four snap-in electrolytics.
