I'm sure this question has been asked a thousand times but it's confusing
for someone like me, who is an electronics nut but not active in the repair
business.

Where in the heck is the best source for service manuals?

I know all the ins and outs about try the manufacturer first etc.....but
certainly there's something out there that puts it all together? What is
Servicemanuals.net?...any good?
Are these just downloadable pdf's they have?

They have what I'm looking for (a Samsung SV-5000w manual).

I wish there was a one-stop source for these....in the past I've either had
to order from the manufacturer parts dept or one of a dozen companies that
only represent certain manufacturers...like Fox electronics etc....what a
pain.

So where do I go?

THANKS !
