Se/30 sound chip warm, weird sounds

[imactheknife]

So one of my other se/30 is making weird sounds. Seems to happen when she warms up. Cap issue?? Rewashed board. I did notice i had a 10uf 16 where a 1uf 50v should have been.

So, i changed out cap.. but still does it. I rewashed board, let dry. The 470uf axial cap is still original

Some up close cap, asc, sony chips pics.. board worked fine for a long time before it started to exhibit this behavior

Well, recapped audio area with new caps. Clean everything really well.. problem solved. So either bad connection or bad cap?

Ok, so i just recapped my other se/30 in the same area as it was more quiet than the working one i do have. Removed old pads, cleaned, new caps, new solder, and she os golden.. amazing what you might have kissed the first time around

It's common to have bad traces or just lots of cap goo in that area, has to be very clean and traces intact or repaired for the sound circuit to work.
