How do I clean the inside of my SX-650 reciever.

I recently purchased a Pioneer Classic SX-650 reciever. I'm from the 70's area and fell in love with this unit back then. I decided to bring myself up to speed on vintage cleaning and repair of this unit and quickly found out one of the first things to do is to find the best way to clean the inside and all it's componets. What is the best way for an amiture to get involved in this process(cleaning)?, and what type of sourses are avalible to learn more about non-professionals trobleshooting and maintaining this type of equipment?. I love the look, feel and smell of this older reciever, as though its a piece of art from the past coming forward to remind us that there is more to electronics than how to make something smaller, lighter, cheeper, faster and possable more dependable. To me its like having a Picasso or Man Ray over a satilight linkup million song chip that you can keep in your ceramic ashtray at home, the one you made while you where temperaraly insane from forgetting your roots.
That could be a hole new subject. Bruce
Bruce, you need to be careful when opening up electronic components if you are not familiar with the inner workings. The power supply capacitors, they look like batteries, are designed to hold a charge and even when the unit is unplugged, that charge can give you quite a jolt. I always discharge them before doing any work on any piece of gear. Once done, I use pure alcohol for cleaning. It can be purchased at the pharmacy, don't get 70%, get 99% pure. Some believe that this is not the optimal cleaner and use the excellent Caig products, available on the net. The volume, balance, tone controls and selector switches can be cleaned with one of the Caig products or spray contact cleaner, such as Tun-O-Wash. Radio Shack has a spray cleaner as well that works just fine.
Great Marty, Thanks for the info. When would there be a need to open up the "power supply capacitors"?, as i don't believe i shall need to on this unit for, the unit was working ok. Bruce
The Capacitors are exposed and not part of the powersupply per/say but look like small beer cans (salt shakers to beer cans in size depending on the product) but typically the tops will be silver and these still have lots of energy that can really hurt you!!!! Stay away from the Caps!
No Bruce, you don't open up the caps, if you touch them while cleaning the innards of the receiver, they can discharge and hurt you. I usually short the two ends with a plastic handled screw driver before beginning any work inside the chassis. If you do not know how to do this, then stop into the local electonics repair shop in your town and befriend the tech. Making mistakes here can be really problematic.
