Well - until I can modify the case so that everything fits (the replacement capacitors are a bit too thick), all the updates that I was planning for my DSD have been done -
.
01.) Replaced all six of the 3.3V LDO regulators (5 on processor board, 1 on DAC board)
02.) Replaced the 5.0V LDO regulator (on DAC board)
03.) Replaced the 45.1584-MHz oscillator
04.) Replaced the 49.1520-MHz oscillator
05.) Replaced the coupling capacitors (between the DAC and LPF op-amps) with 100uF 25V Roederstein EB axial capacitors
06.) Replaced the LPF op-amps with MUSES8920E
07.) Replaced the 22Ω series resistors for the Balanced 2.5mm TRRS output with paralleled 10Ω resistors, to get 5Ω
08.) Replaced the op-amp socket with a low profile version
09.) Installed a MUSES8920E on a DIP-8 header, in the socket
10.) Replaced the 470uF 10V coupling capacitors for the Single-Ended 3.5mm TRS output with 1000uF 10V capacitors
