Ok - so, I was given a cosmetically near perfect CA-800, that the previous owner said died "after too many speakers were hooked up or something". I took it home, cracked the case, and found 2 blown 3A fuses on the left channel.
I replaced the fuses, hooked it up to a DBT and powered it on. At first, no reaction from the DBT, the power LED lit, and the relay clicked out of protection. I was fixing to hook up an Ipad on the AUX 1 input when DBT went bright and the relay clicked into protection. I had my hand on the switch so was able to shut it off right away.
Removing the left side fuses, I can power on and play with the right channel only. However, the music is distorted.
I'm going to presume that I have at least one output on the left side that is bad, and will pull and test them following Echowars helpful thread on the subject.
I've never worked on a Yamaha before, but this unit seems well laid out for maintenance and I was able to find the SM in the AK database so I think I've got a good handle on it so far.
As I've only done a few Pioneer units and a couple of Sansui's, I'm wondering if there are ant tips, tricks, or "well known" issues that would be helpful when working on a Yamaha (Sansui glue and fuse resistors, for example).
Also, I'm kind of curious as to why the right side is distorted.... could that be a function of the left side being off-line, or does that infer a problem on that side as well?
Any advice, guidance, or constructive criticism will be gratefully received.
