I need an instuction manual for a Marantz SR685 audio/receiver
Getting replacement instruction manuals are quite easy. The best place to replace the instruction manual is from the website of the product manufacturer. Simply go to the website of the product manufacturer and from there check for the customer support page user manuals are usually filed and kept for download from this page.
Or you could simply type the product make and model in google and add manual to it. EG: Marantz SR685 user manual
Hope this solution has been helpful?
