I will include surprisingly well-written instructions, but this is moderately complicated, and you should know what you're doing and have a decent soldering iron and a dim-bulb tester with a 40W, 60W, or 100W incandescent bulb. This kit may not fix your receiver, but it's pretty likely that it will, and it will definitely help it run better. Please see my pictures for details.
US shipping and handling is $8, and international is $28. If you have any questions, please ask.
