Restoring Roenish Hupfeld DEA in Lisbon
By Miguel de Mattos

I have a player piano to restore, but this one very different from
all the ones I've ever done.  It's a Hupfeld DEA system in a fantastic
Roenisch upright piano.

The rolls are huge, about 46 cm, and the tracker bar has 106 holes,
with an additional three holes in the center under the regular ones.
The player action is under the key bed.

It's a reproducing piano, no doubt, but very different from the
Hupfeld Triphonolas.  Any comments are welcome.

Regards to all
Miguel de Mattos
Lisboa, Portugal

 [ Claes Friberg writes, in Bowers' Encyclopedia, p. 311, that Hupfeld
 [ developed the DEA system in 1905 to compete against the Welte-Mignon
 [ reproducing system, but "DEA was more expensive [and] production was
 [ discontinued just before the First World War."
 [
 [ Friberg says that "The DEA reproducing system is a rather
 [ complicated device, but when properly adjusted it will play as
 [ well as any properly adjusted Welte-Mignon, Ampico, or Duo-Art --
 [ and, as is the case with the other systems as well, there are
 [ enthusiasts who believe that the DEA is superior."
 [
 [ The Nethercutt Collection at the Merle Norman Museum, Sylmar, CA,
 [ displays a DEA Vorsetzer and, I'm told, owns a second Vorsetzer.
 [
 [ Are there other DEA's in North America?  Elsewhere?  Is there an
 [ MMDer, familiar with the DEA system, who could offer restoration
 [ advice to Miguel?  -- Robbie
