This is my extremely rare Deltec PDM1 DAC unit.
When I checked with Martin at http://www.acoustica.org.uk/DPA/deltec.html , he advises my unit is 1 of 81 ever manufactured by Deltec!!!
All was required was to recap the 4 power filter caps on the motherboard, as before the olde DAC needed atleast an hour to warm up before she sound right. Sounds absolutely devine upon power up.
I did add 5 heatsinks to the power regulators as they do run hot. Not sure why the heatsinks were not installed in the past.
Currently paired with my Leak Delta 30 (original condition) and Denon DVD2900 (modified) as transport.
