Hi,
There's so many posts about this card I feel sure I've missed something. Please let me know if there's a modification I've missed. Here's a list of the mods I've done so far:
replace the oscillator with a low ps/ppm tcxo
replace the ceramic caps in the feedback circuit for the I/V op amps with metallised poly~ caps
boost the -12v to -15V and fit a 7912 regulator
remove the output coupling caps on the line out
use a linear lm317a or similar psu
upgrade the analogue section's decoupling caps with SilmicII
replace the op amp sockets and select some higher-performance op amps or discretes ( I'm using LME49720HA in I/V and dual AD797BRZ in the buffer ).
Have I missed anything ? Or is it finally finished ?
