Sansui au317 integrated amp, and Sony 707 CDP.
Correct I shorted one of the stereo inputs to the integrated amp from the cd player "out put".
By half the signal, I meant that the "presence" is gone,example, Miles Davis "A Tribute to Jack Johnson", the opening tune,"Right Off" opens with a guitar riff, 3-4 minutes later Miles joins in, trumpet should be "upfront", it is barely audible, also on Chic Corea's, "Return to Forever", opening tune,"Return to Forever", Flora Purim's vocal after 3-4 minutes starts, should also be "Upfront", again barely audible.
This condition is the same on "Aux, Tuner and Tape inputs".
As I said the headphone output is fine, I built a patch cable from headphone jack to speaker terminals.
All inputs are working fine with speaker switch set to headphones, A&B speakers off.
My volume setting was normally at 9:00, now it is at 12:00.
Looking at the schematic the headphone Jack inputs come straight off the speaker switch, after the output stage.
I am no means an expert with schematics.
I have a "Heath Kit" Breadboard with a variable signal generator, a 2 channel oscilloscope and a digital VOM.
Also I have the "Heath Kit" Electronics Course to use as a reference.
I hope to signal trace with this equipment.
I have been making cables for the signal input and output for my scope.
I ordered a temporary receiver to listen to while attempting to figure out this problem.
I hope this description makes more sense to you.
Thanks for your response and suggestions...
From a fellow tweaker.
