#8 solder tab

Ah, it looked a little funny, but now I am indeed remembering that the standoffs are uneven without it!  Sorry to bug you about that.
 
Just did the resistance check - all good.

Voltage check - all good except for terminal 17, which is supposed to be 0V, I am getting 15-25v.  Any ideas?

Thanks!
 
Two popped I think.  Going to need to order replacements, but will turn it off for now until I figure out what's wrong with it.
 
You'll need PB to diagnose this, but to get the ball rolling I suggest you post pics of the pcb board, the terminal strip with T17 and the D 4-pin socket.

There's a 249K resistor from 17 to 16, then a black wire from 16 to ground.  One of these is probably not connected.

Posting photos would be a good idea.

LEDs explode when there's an electrically egregious miswire (usually).
 
Ah, so the half of the C4S that feeds the side with the problematic voltage is OK.

It would be good to see the other 4 pin and 9 pin socket where that half of the C4S board feeds.
 
Somehow I am having difficulty uploading pictures. Will do so later. Thanks for all your help!

The explosion might have gotten me banned from experimenting with DIY at home for a while....

PB, do you have an idea as to how long repair might take, if I decide to send it for repair?

Thanks!

My bench is pretty jammed right now, as a bunch of repairs rolled in almost all at once, but they should be clear in a week or so.
 
I see a lot of little pointy bits sticking out that need to be trimmed.  It's quite possible two of them are touching (the one I noticed most quickly was around terminals 6 and 7).

When I see something like this, it is nearly always because the wire cutters used weren't side cutters, so it just ends up being really difficult to get in and trim things up properly.

I see a lot of cold joints. The red wire connecting to the 4 pin socket is an example. I'd suggest reflowing your joints with a little more solder. Make sure the solder flows into the joint and creates a fillet between the wire and the terminal.
 
Thanks, Doc! Although I would have loved to continue to work on the Stereomour until the problem is fixed, I have decided to send it in for repair. The explosion of the LED, while minor, caused some concern among the household so that is the way we decided to resolve the issue. Living with others is all about compromise!
