One channel of the UcD in test tonight. Took me some time to find the connectors for the input. The are supposed to be Molex KK 2.54mm or 0.1" series. I did not have enough quantity to order online from RS or Farnell, so had to search for compatible ones from Koba. Found the connectors there, but eventually, had to use them without the housing as this offered better connection. The mechanical construct of the housing did not render it to reuse that well after stripping the previous wires and replacing them with the mundorf silver/gold wires.
Then, it was the single ended RCA to XLR connections that caused me to search high and low for the reason why no sound is coming out from the speaker... I shorted pins 1 and 3 and used it as ground. Pin 2 was signal. But no effect. Actually it was because there was a internal lift up /ON pin on the UcD module that had to be grounded or connected to J2, pin 5 of the SMPS module. Need to get some more connectors to do this nicely.
Well... at least it is almost there... Before Chinese New Year.
Some pics here.
