Question about Audio & Video Receivers
You have a worn power switch. After 30 years of turning a powerful receiver on and off, the contacts in the power switch become pitted and corroded, and just plain dirty - this is exacerbated in smoking environments. As the resistance in the contacts increases, it takes more "juice" to bridge the contacts, and this takes the form of hissing and sputtering. The best solution is to replace the power switch. These can usually be found on eBay for between $10 to $25 - just search for "Marantz power switch". You'll probably need to disassemble most of the front end of your receiver to get at the switch, and you'll need some soldering experience and tools to remove old and install the new. Once you do the job, however, it should last the rest of the life of the unit.
