Well, I finally got around to upgrading the diodes in my QDS-15 cdp. The difference was not subtle-it was Enormous! The left channel is dead! After taking it over to my friend's place this morn. ,(he has scopes and other test equip. which I do not have and he knows how to use them), we discovered that the left output of the dac chip has failed-basically shorted to ground. I have ordered 3 new chips, (just in case), but the problem is how to/where to get the new chip installed. It is a Burr Brown 1728 ssop, and it is very tiny. No soldering iron here! Up here ,(near Toronto Can.), I don't know of any shops with the equip. to do the job. My friend works for a computer service company,(actually he's the V.P), and says that they do work with sop chips and maybe they will be able to do the work for me. I was extremely carefull when swapping out the diodes, and according to our testing this was not the cause of the chip failure. I am quite confused, not to mention even more upset about the whole situation
Anyway I'll stop my blubbering now.
