AFAIK, the NAD 304 and 314 are electrically identical. The sheet metal chassis are a bit different, and the 314 front panel does not have a Soft Clipping LED. My 304 was built in the Philippines, while this 314 was built in China. Cosmetically, it is in very good condition. The front panel has some imperfections and the Top Cover has a slight deformation along the front left that is hard to spot. This unit was originally wired for 240VAC, but I have replaced the power cord and modified the Power Switch Board for 120VAC operation per the Service Manual.

I also installed a new power switch. Knowing how good my 304 sounds, I couldn't resist upgrading the caps in the audio sections of this 314.

The coupling caps are now all nichicon Bipolar, with nichicon Fine Gold and ELNAs used elsewhere. As preventative measures, I have upgraded the Speaker Relay from 5 amp to 8 amp, and upgraded two resistors in the Power Amps known to fail from 1/2 watt to 1 watt. The switches and pots have been cleaned with Deoxit D5 and Fader F5.

I even performed a mechanical upgrade by squeezing each Input Select Rod to its switch with cable ties. I was noticing that each time I changed the input selection, the unselected Rod would pop out slightly and partially separate from the switch; a silly failure just waiting to happen now avoided.

The 304/314 are an all-discrete design featuring the same 4-transistor Phono Preamp utilized from the 3020A and into the Monitor Series. AFAIK, these amps were also the first by NAD to feature a Class G Power Amp design before the "Power Envelope" terminology became popular. This early design also appears to have focused on "speed", as the pre-driver transistors in the Power Amp are HiDef Video drivers with an fT of 150 Mhz.

This little beast is ready to PLAY! Please message me with any questions, corrections, etc.
