Repairing Vintage Audio Gear - NAD 7100 - It Lives!


I'd been using an Onkyo SR309 receiver with my PC setup for around 18 months.  Being that I spend a great deal of time at the computer, and my music collection is on the computer, it's the listening location of choice.  The technical requirements for audio gear hooked up to my PC isn't anything special since I only use stereo (left/right channels only) sound.  Really the only thing I need besides decent power and sound quality is a digital optical input to receive audio from the PC.  Because of this I've never invested too much in my audio gear.  I might have spent $170 on this Onkyo.

Then one day I power it up, hear the usual series of relays inside it clicking on, but no sound.  Trying all sorts of inputs/outputs and testing I come to realize that something isn't working on the amplification side of the unit.  Unfortunately it's not an obvious blown fuse, or resistor that I could easily track down and replace myself.
