Ok, so let me start off by saying how cool it is to be able to ask ppl for help on things you love. Just got on here not to long ago and already finding out that most everyone is legit about helping, the new kid. Brand new into audiophile. So another request. I recently came into possession of Nad 7150, Nad 6050c, and Nad turntable ( I’ll post model number later) got all three for 100 bucks. Super excited, so excited in fact that bought em without testing. They all cut on, but sad face,.. they are gonna need some tlc. No one in my area repairs vintage receivers.
now, I also have like 11 tube radios from various times and have taken on the mantle of soldering and changing out tubes and capacitors. I want to fix these Nad because , why not right? I believe I can and if they can’t be fixed well at least I can sell for parts. I’ve looked everywhere for 7150 schematic but unable to find anything it 7140, does anyone have any input on my repairs? I can send pictures of insides if that helps? Any feedback would be greatly appreciated. Anyways tell me if I’m nuts or if there is no fix or if I just blew 100 on Nads, for no reason. The 7150 is gonna get a really nice cleaning with deoxit. Also gonna get the other with deoxit too. The selector knob won’t select. It just stays on the tuner. Tuner won’t tune or if it does I can’t hear it because it seems like aux/phono/tape/ dont work either. I can ther sound period from any speakers. And The tape deck buttons are very stiff, deoxit should(I’m hoping ) get them back to normal, but tape won’t spin, hoping it’s just the belt. Thanks!!!!!!
