Concerning addition of a Recordo expression unit to regular player.
You might want to investigate a past AMICA bulletin from way back or the
Billings roll book, which describes Recordo expression units.  They seem
to be the supreme Recordo enthusiasts.

I have one spare Recordo expression unit made by the Motor Player Corp.
if someone wants it.  I will never use it.

 [ Anybody know how to get Billings' book with the Recordo information?
