Yamaha CR-620 Balance Knob

My 620 has the cracklies in the right channel when sweeping the volume between 0 and 2.5. I've put quite a bit of DeoxIT from the inside and there's only a slight difference. I'm wondering if removing the volume knob AND balance knob would make a difference? In other words, is there any point spraying from the front?

Also, does the balance knob just pull out? It's not as easy as the volume.

Thanks!

No point. The potentiometers carbon resistance pad may be damage or still dirty.

Ok, thanks for the info! Saves me some trouble. I think I'll just leave it. It doesn't affect the sound, at least. Maybe I'll give it one more soaking in the near future.

Edit... It occurred to me that I didn't sweep the balance dial when DeoxITing. Oops. Considering it's only on the right side, I think that's a necessary step. I'll do that next time around.

Well I sprayed a lot inside and waited two days (yeah I know it doesn't have to be that long). I turned it on, and the crackling was a tad louder. So I opened it up again and sprayed a little more, this time rotating the balance knob, in addition to the volume (as mentioned above), and waited another 48 hours. It was even WORSE. This time the crackling was in the upper range of the dial, instead of the low range, and it was louder.

So I pulled both vol/bal knobs off, put some tissue underneath the potentiometers, so the stuff wouldn't drip down inside, and sprayed while rotating the vol/bal. When I removed the tissue, it was full of black dirt...And everything was much shinier I might add.

Anyway, no more crackling. And the reason it was worse before? I forgot I had previously squirted a tiny bit in the front (with the bal knob still on) but not much. What probably happened was it just shifted some of the dirt, thus the difference in the crackling and range.

So my recommendation to anyone with crackling issues... Squirt the front first. It might be all you need.

Well you did get it done! For most gear there is no substitute for just getting right to it and dis-assemble what's needed to get at those pot openings,spray,and work the heck out of those knobs and buttons.
