Hi,


has anyone modified either the Aux (100mv) or CD/Aux (300mv) input
modules on a CD input for better results with highish outputs from
CD/DVD ?

I don't have a low output radio and so replaced the 1M shunt with
470K, but still not too much control. Before dropping to 100K or even
47K I thought I'd see if anyone has found the best balance. I also
noticed that the potential divider on the TL072 output on the aux and
CD/Aux are different ? Anyone experimented. I have 2 CD players and a
DVD player, but there output levels appear to differ considerably.

BTW I *know* the current religon is to replacxe the OpAmps, but I'm
sticking with the originals as they sound fine to me, just want a bit
more control on volume.
Yes, I have converted an early Radio module to the CD module. I had a
genuine CD/Aux module from Quad and just changed the older module components
to suit. The component changes a
Reduce R200 & R201 from 1M to 470K (you've done this already).
Reduce R202 & R203 from 2K2 to 1K5
Reduce R204 & R205 from 3K3 to 820R
