If this is a solid state (transistor) amplifier, that should do it. If it is a vacuum tube device, add some toothpicks and a pencil eraser to the list. Before I can tell you what to do, tell me what you're cleaning and whether it has been running for more than a few weeks. Also, how adept are you with just basic skills with electronics and why you want to clean this receiver. Is it just dirty or are you having problems that need correcting? |

Use a full Q-tip for the outside of the connector and strip off most of the cotton to get to the inside of the positive connection. Do this with the receiver's top cover off so you can see what you are doing. Blow any accumulated dust off the components with the compressed air. Any press-on connections inside the receiver should be cleaned. Take the can of spray cleaner to the controls and move the volume, balance and any switches as you spray inside the housing for those controls. Do not spray anything into the tuner assembly. Use the minimum amount of cleaning fluid to get the job done. Drenching the inside of the receievr with fluid will not be of any help once the connection is clean. Do not take any sort of abrasive cleaner to the connections. Since these will be nickel plated jacks, you can get a reasonable amount of gunk off the jacks but they will probably not return to like new condition. Clean until no more oxidation comes off on the Q-tip. The best cleaning fluid for this job is Pro Gold which can be purchased at Audio Advisors and several on line sellers. If you have a pro audio shop in your area, they probably sell Pro Gold over the counter. http://www.audioadvisor.com/store/productdetail.asp?sku=CAIPG7.5ML |
