I have a Kenwood KA-3020SE amp which is causing me some issues, I think due to dirty switch contacts on my input selector switch. Lots of crackles through the speakers. Can anyone recommend a good product to clean these?
Thanks.

It's half way around the world, but you just offered a Scotsman a freebie.
We don't have Radioshack, but I'm sure Maplin will have the stuff I'm after.
...Contact/Control Cleaner and Lubricant spray which you can easily find and that works.
Take of the top of the unit and spray it into the openings in the back of the pots.
I use a product called Caig Deoxit. I would do what the others recommend and get any contact/tuner cleaner. If the problem persists you will need to replace that pot. The wiper and contacts do wear out.
Until you get into some of the wickedly expensive snake oil I've found that pretty much any generic contact cleaner available at your local electronics emporium will get the job done quite nicely.
The key to the whole thing is to do all the pots and switches while you're under the hood and to spend a few minutes working each of the control knobs back and forth (sort of masturbatory thing).
Working those controls is important. I find that many folks find a setting they like and tend to leave all the controls at that position - where they accumulate all manner of buildup. So sometimes, what you think is an issue with (say) an input selector, is actually a pot somewhere downstream that is the problem!
Give it a go and let us know!

You need some spray tuner cleaner. You can pick it up at any good old-fashioned electronics store. A fews years back I decided to be paranoid and suspect they were going to take this magic stuff off of the market, so I bought a whole bunch of it. What I'm trying to say is that if you want to swing by my house I'll give you enough to last a lifetime. ;~)
The spray is especially handy
