Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
I purchased a vintage Sony mixer off eBay and within the hour was able to locate and purchase the manual for it.I mean really,where else can you find a manual for a product made in 1983!? It was easy to find and purchase/download the manual I needed.I will use this site again for other equipment I have! Great site!
It`s full copy of a service manual from url http://www.philips.owner-manuals.com/PM3216-service-manual-PHILIPS.html
