ДАВАЙ-ДАВАЙ

My NAD 3150 (cheaply bought 5 years ago from an auction site) was scratching when adjusting the volume and balance control, sometimes loosing output completely. I have unsoldered and dismounted the control, cleaned it with a contact spray and compressed air, then resoldered it. It now sounds much better, will see if this fix will last. What’s cool is to see how easy such a fix is possible on a 20 years old electronic device. I guess that today’s devices would be impossible to fix so easily.

Now the next problem is the tweeter of my right loudspeaker (MB Quart 280). Looks like I will dump them. Even if I would find a replacement tweeter, the suspension of the boomers is probably already long dried.
