Amplifier maintenance for beginners


What kind of maintenance is recommended for beginners? Can I clean the circuit boards, or output connections? Is there something called contact cleaner?

Carefully vacuum out the dust bunnies and cat fur about once a year. Every month or so gently wipe the exterior clean using Windex.
Come on, Snofun3! Are you trying to get this guy a repair bill? You need to change the oil in your amp much more frequently than every 6K miles. Sheesh...
Sorry - I was thinking about using synthetic oil.

OK, One more tip - if the voices don't sound centered from the speakers, ensure you have equal tire pressure all around.
No, I'm the one who should be apologizing! If you're using synthetic, 6000 miles is quite conscientous.

I must admit being more than a bit lax on checking my tire pressure, though. Especially, with the weather changes we have here in the spring. I just kind of blissfully kept listening...
Make sure the tire pressure is checked when the tires are cold and not while you are driving around, half a km is the extreme if you need to go to a gas station. After that the tires get warmed up and you get incorrect reading.

As for your question the best answer on this thread is "If if ain't broke don't fix it"
