Best way to clean this...

[jplinville]

Old Kenwood 50 FM stereo. I'm getting a hum on the low range, and little to no bass. Inputs are heavy on one side, but weak on the other. Caps look good, no leaking, no bulging. Not sure what's causing the hum, maybe it needs a heavy cleaning.

Many years of dust and such has accumulated on the inside. I've taken compressed air to it, but there's still a good amount there that needs cleaned.

What product is good for cleaning this? Will MAF cleaner from an autoparts store work?

Deoxit should help. Does it have a balance knob? That might need cleaning or be the problem.

MAF cleaner might be a little harsh for that. You may want to try electronic contact cleaner instead.

Try Techspray Blue Shower II. It has an ethanol content, so don't go crazy on the pc boards.

It has two part knobs...center and ring are adjustable, but work together.


Thanks for the suggestions, guys. I'll give it a shot.
