Hi,
I have a CD624 which I found to be best in any class by miles some years ago when it appeared ( an 'integrator',
1 bit player). I asked for a circuit diagram via customer support which promised a response in 48 hours........over a week and counting...........
Would like to fix since choices of kit limited in NZ. Have found a diagram on the interweb and slowly going through measurements, display voltages seem okay, have to go through the other supply voltages (other than TTM I guess) .
Any thoughts welcome if anyone has come across this before.,
/cheers tim
