HK 330i

[RAMBIS50]

I have a HK330i. Had it for years. Use in my garage "cave"... it's been great, except for one quirk... when adjusting the balance the sound will cut in and out and sometimes becomes muffled. I have to very delicately adjust it to get the full stereo sound back. Any idea what is causing this and how can I correct this?

Thanks.

That potentiometer is dirty/corroded.
It's a common issue with electronics as they age. It should be easy to remedy depending on how handy you are with a screwdriver.
You can clean the pots with deoxit.
You can prevent the buildup of corrosion by
turning all of the pots and pressing all of the
switches every so often.

Read the first page of this thread, don't worry about the other 28 pages. It should get you started on cleaning controls. And if you deide to clean the control, clean any others you can while "in there".
Good luck.

What is the potentiometer?

In this case, it would be the thing your balance knob is connected to that directs the music energy to the left, right, or both speakers.

If these potentiometers get dirty or corroded, the music energy will have trouble passing through them.

That video shows guitar controls, but it's pretty
much the same process.
