Hello everyone, I wanted to first apologize for the long-winded post. I've had a NAD C326 BEE for about 10 years, of which hasn't been trouble free. The first three years were great. Then, it started with the control panel not working correctly. The buttons to switch sources wouldn't work when pressed, yet would work with the remote. The sources would however automatically change when trying to listen to let's say a record. Then the same thing happened with the power button, it no longer worked except with the remote. Eventually, I had to shut it off on the back of the amp because after shutting it off, it would come back on. The next thing to go was the balance control shorting out, where only one channel would work until the knob was rotated several times. After getting tired of it cutting out, I took out the balance control and wired it directly so there was no balance control.
I've taken it apart and re-soldered places where it looked to be suspect--including the relays. It worked for a day or two then would switch again and or randomly mute.
I suppose why I've kept it for so long is because it was my first expensive to me amp, the sound is incredible (when it works), and I thought it was built to last--little did I know.
I would like to fix it, but I have no idea where to start. I have a volt meter and esr meter. No scope.
Thank you again in advance.

Sounds like you got hit with NAD's parts quality pretty bad there. That's not one of their great strengths as you may know by now...
The button issues, possibly you've got a switch that's internally shorted and blocking everything else. Does sound like switch contact issues / bad solder joints / cracked traces or something of the sort.
I'd say obtain the service manual and study that first. It's definitely up on HFE.

Thanks, sgrossklass for the response! I'll download the service manual to see what I can troubleshoot. This is a nice start. I suppose if all else fails, I can at least salvage the torroidial power supply and buy a kit that would work with the voltages.
