SRKU-1CT-SL-24VDC Automotive Relay, SPDT-CO, 24VDC, 45A

These will replace the two relays in the NAD 2200PE power amplifier almost perfectly. You will have to enlarge two of the holes on the circuit board as two of the pins are a little two large to fit. It is also recommended that you replace the 470 ohm 2 watt resistor with a 240 ohm 2 watt resistor after installing these relays. But instead of removing the 470 ohm resistor, you can just solder another 470 ohm 2 watt resistor in parallel with it and this will give you a 235 ohm resistor. You will need to order two of them. For more information on how to replace these relays just go to YouTube and search for "NAD 2200 Protection Relay Repair".

I purchased 2 of these to swap out my failing relays on my NAD 2600A amplifier. They work perfectly. If you are having the issue of intermittent sound / cutting out / fuzziness on either or both channels of your NAD 2600A amp, most likely, the old relays are to blame. Some people say to drill into the board to make this part fit - as two of the prongs are slightly wide. I wouldn't do that. Instead, I just got a metal file and filed the prongs down on these new relays to fit the holes in the circuit board. Took all of 3 minutes. Highly recommend, saved a great piece of gear!

I used these to replace the original speaker protection relays (2) in a NAD 2200 Amp that I purchased off of Ebay. The Amp would intermittingly start up without one of the channels. When I'd turn up the volume a little, the channel would kick in. These and a resistor fixed the problem. Two of the contacts on these relays were wider than the holes they were to go into. I used a Dremol to sand those and make them fit. Some chose to widen the holes on the circuit board, which I find too risky. This 35-year-old Amp is in mint condition and sounds incredible.

I recently discovered that my amplifiers dropout issues were due to open frame relays oxidizing, poor or no connection. The NAD 2xxx series of amplifiers have a known issue of protection relay problems. I viewed a "You Tube" video that clearly explained the process of the repair. I replaced the original speaker protection relays on my NAD 2200 PE with these new ones. Wow, the amp really came to life, sounds like new. I am rediscovering how much I love two channel systems. Now I have a strong stable stereo image, no fading of the sound from one channel. Sometimes I would just completely loose a channel. I wise I stumbled across the video sooner, as the amp has been giving me trouble for the past decade. I think that this new relay couldn't have an oxidation issue due to the fact it is sealed. Only time will tell. One thing I can recommend is repeating what the gentleman said on the video, "make sure you turn down the volume on your preamp before powering off you amp" - should reduce the chance of arcing on the relay contacts. If your NAD 2200 is giving you dropouts, get a qualified technician to fix it for you, you will be glad you did.

Saved myself a grand by not having to replace my NAD amp.I squeaked several extra years out of it by cleaning the original relays periodically, but even that was not working lately.When the problem first developed the only option was to have it professionally done for a couple of hundred dollars , plus shipping. Then I found these on you tube and put them in about a month ago. They have been working flawlessly. They might have even improved the overall sound ( but obviously I can't go back and do an A-B test on that)

Seems to fit correctly, I haven't installed it yet so I don't know how well it works.

I used this relay for a Nad 2200 Amplifier !Works Great

Work great. Used these to replace some worn out protection relays in my NAD 2600A stereo amplifier.
