NAD part needed 7175
I am repairing an NAD 7175 reciever.

The Speaker select switch has a bad contact.

It has "A B Off A+B".

The switch is rotational, but has rectangtlar body.

Any idea guys?

I bought a couple parts to repair my NAD 7175PE more than a few years back. I was able to order them directly from NAD. I'm not sure how I got the number... and unfortunately, I don't seem to have it handy any more.

Do you happen to have the service manual & schematic for your 7175? I've also misplaced mine. That's probably where I scribbled the 800 number for the parts department. Anyway, I'd like to find a scanned copy of the schematic. I'd like to disconnect the main power amp, since I only use the preamp section of it anyway.

I do not have a copy of that schematic, but I did talk to NAD, they did not have the selector switchs I was looking for.

The are NLA.

But I found this same amp on Ebay for like $150. It isnt the highest end amp they made I gather...

I've found my service manual for the 7175PE. Let me know if you need any information from it.

is the switch actually broken? or are the contacts open?

The switch contacts are are open. I took apart the switch and the contacts are burned. Usually because the switch is turned while the sytem is turned up.

I have the switch bypassed.
