Question edited for a lot more clarity.

Probably easier to buy a new refurbished one for $45 and copy it. There is no Service Manual for it, just the Owner Manual.

Very easy to fix. Download htr5740 service manual.Locate speaker relays exchange the front speaker relay with the REAR ONE. If sound comes out from front left and right speakers but no sound comes from one of the REAR speakers. The defective component is front speaker relay.
Replace the relay will get it fixed. See service manual
P.82. Yellow circled is front speakers relays
When av-amp used more than four years, relay contactswill be oxidized, making bad contact.

This is the best I can do for you. I don't see any free manuals on line. In fact, I am hard pressed to find this anywhere else. (Vintage Manuals in Indiana appears closed, although you see web references to it.)

Take some voltage reading according to the manuals.

It should say next to the speaker terminals what impedance of speaker the amplifier is rated for. You can drive any speaker within reason with just about any amplifier as long as you are not trying to attain loud levels. Here is a link to the service manual for your amplfier. It states in the schematic power ratings for 2,4, and 8 ohm speakers so you can assume that this amplifier is compatible with those impedance speakers. NAD is generally known for their beefy amplifier sections. http://www.scribd.com/doc/7234868/NAD-3020-Service-Manual
