I found the old photos today on an old portable hard drive.

could be the speaker cable..or something loose,or cold solder joint. Thats what it sounds like.. sometimes the componets are soldered good,but just the vibration ,the leads and caps vibrate,tubes or retainers,and pick up a buzz or noise. Theres alot of vibration going on. Combos are known for this happening.
Some people use silicone type stuff to put on the caps or resistors.

It may sound crazy,but when you look at a layout or schematic,you just see the parts, the things you don't see are how the components can vibrate and cause noise. Some things i do, is use rubber washers under the boards mounting bolts. You could also strip some solid core wire about 18 ga. and use the insulation to slide over the leads of the caps and resistors, this will help,and make sure the leads are pushed down along the board. I'm sure there are alot more methods,but these are some that help. Sometimes its a little more extra work but it helps in the combos.
