First amp on the is the one I got from eBay. The second (cleaner label) is from the amp in my car.

In theory- the one from eBay should work, correct?


my if I plug in my original amp the sound is crackled and I get the constant thump. Upon opening the amp I can see where the board burned from a capacitor.


The one from eBay I plug in and I get no sound at all. Identical to what happens when I do not have an amp plugged in. The board looks mint. Not sure if it’s simply a part compatibility issue.



Regardless I’m over it and I’m going to take it to a car audio shop to just install a new head unit. I loved the oem look but I’m not an audio expert and I’d like to have audio on the days I choose to drive it.

I just did some research on this so 120 is 92-94 then they have 190 which is 95-99 and 220 is the 98+. Getting the same one would work, but you can also swap in other ones as I found out other amps offer different sound tuning

This Post is about the Nakamichi Radio Setup that some of us are clinging to.
Amp Part numbers as Goes
86280-24120 92-95
86280-24190 94-99
86280-24220 98+
But all amps with all years since the same 3 cables

My AMP is slowly making the whining sounds but not often so im getting the signs. I got an amp 86280-24190 as a spare and i just plugged it in today and it's a WORLD of difference compared to the 220. The 190 has higher mids, softer lows and stong highs, vocals are pushed a bit but can sound a harsh depending on how well the master of the track is. I listen to drum & bass, deep house, jazz, and a mix of alot of the things and sound tuning is completely different compared to the 220. The 220 has stronger bass (Like rattle the car), the vocal aren't pushed as much, but this depends if you have stock speakers or not (i have JL Audio C2-400X in all four corners) the mids are pronounced and its just an overall modern tuning that supports todays music. If anyone has the nak system still, get a 220 amp, you experience will significantly change, even if you have blown or lower quality speakers. So the main thing i noticed even though i dont have a first gen amp to test is the tuning is main difference. So if you're looking for an amp 220 is the way the go.

Can I use this thread to ask for a Nak Amp 220? Looking for one myself.

Thank you for sharing. Do you have a working (ie, non blown) Nak 220 for sale?

Any idea how they decided between the 86280-24190 and 86280-24220 in '98 and '99? My '98 had a 86280-24190, which I didn't find lacking in the highs or lows, so I would guess your new 190 is faulty.

I would like to know that as well. I didn't know the tuning was different until I heard the 190 vs the 220. I even played drum & bass in the car which has a lot of soundstage and it sounded significantly quieter than my 220. The bass was there, but as profound as the 220. The 220 can vibrate the whole car depending on what you're playing. The 190 at the same volume level, not even close. Im wondering what the 120 sounds like at this point

Again, you're making a questionable assumption based on a 25-30 year old amp (that's notorious for failing over time) that you don't know is functioning properly. If you didn't demo both of them new, you have no proper basis for comparing them.

Yeah very true! I gotta find someone who can add new capacitors for a true test
