Reliability now and for 20 years from now (knock on wood). Good job in keeping this vintage stuff from ending up in the landfill. It's a shame when something that is of high quality gets tossed out when it could be restored to its former glory and enjoyed for another 40, 50 years.
Of course a recapped Marantz sounds healthier, more clean, defined and detailed, but somehow the muddy, warm sound of an old / original Marantz has its magic
I think the restored version sounds brighter. But very hard to compare through a mic, compression, youtube. I love the effort though, I have wondered the same thing myself when doing a restoration. Great work. Keep it up!!
Hi and congrats for restoring vintage Marantz. I do listen a subtle difference where in the before trial the bass is a bit muddy and mids less present, also treble is not in focus. In the after one the bass is more tight with better mids presence and great treble both precise and in focus. Something similar happened to me when I restored my Pioneer VSX-D1S listened through an excellent pair of B&Ws. A better experience all around indeed. Besides it will last another forty years!! Thanks
I could hear a stunning difference. The sound stage was wider and there seemed to be a touch more reverb in the rebuilt model. Both sounded slightly muddy on the low end but that is to be expected with everything set flat. I really enjoyed this video. I subscribed and will watch more as I am starting down the path of learning restorations myself. Thank you!
Great job! I am listening on a laptop so I can't tell any difference, but later I will listen on my home computer that is connected to a 1983 Harman Kardon PM 650 amp and JBL speakers. I bought my first system in 1975 when I was in the Navy so I love vintage audio.
I honestly could tell very little difference from before and after but that in itself I feel is a testament to how well Marantz used to be, quality-wise.,
That sounds absolutely amazing man!!! Well done! I have the same problem of having large speakers on my bench for testing purposes. Those KLH's will absolutely come to life if you move them away from the walls, but unfortunately the real world doesn't always allow that to happen😒 great video man!!!
Clear difference. I'm listening with a quality headphone amp and DAC it's very clear the rebuilt Marantz is better. Detail, (quieter background) extended range little grain or hardness now. The dynamics are better too. How many hours has it been ran after the rebuild? Once 100 hours are past it will sound better as it breaks in. The first music choice was good for a comparison I enjoyed it. I bought a lower range Marantz receiver in 1974 at the PX in SE Asia. I truly wish I still had it.
2215 original sound is not "detailed", with "punch" and "clarity". Is round, deep, neutral, musical as well, with sweet hi region....and especially BALANCED!!!! Not with mid-hi in front of you and agressive! Now....it sounds like Technics entry level. :(
I like that your evaluation, the sound is the the same before and after restoration. Most of us are watching on a laptop with crap little speakers and there is no way we will hear a difference. I have thought about trying to re-cap some of my vintage receivers and speakers, but why? If they are working, they are working.
I am amazed at how good the unrestored sounds. The adage of they don't make them like they used to certainly apply here. The really don't sound any different. The restoration is just there so you can pass it on.
Man it sounded great like brand new. Can you please feature how to restore a Sony FH80 stereo component, the crispness of the sound is gone. Thanks and Godspeed
I too like the Loudness button on my Marantz. You mentioning it reminded me that I turned it off in October when I was watching a movie. Guess I don’t depend on it since it’s been off for four months but it is cool…despite all the “audiophiles” who say otherwise.
@AH-Fix-It I agree with you entirely. I really couldn't hear a difference between the before and after, which is definitely a compliment to your restoration skills and I thought it sounded fantastic both ways. Full disclaimer though. I listened to it through my pc, which is connected to a Topping D10 DAC, which is connected to the Aux in of my Kenwood KA-660D, which is running Wharfdale Diamond 9.1 speakers, so is most of what I'm hearing a result of my setup? Most likely, but it still sounded fantastic to my ears and as always, I'm really enjoying your videos and hope you keep them going for a long time to come. :-)
I wish I didn't know which one was before and after, my expectation bias is now engaged. However, I think I hear more damping and less tubbiness to the bass in the after version. Tone sounds the same, just more taught and controlled. Would have liked to see tone bursts on a scope for objective evidence of what I "think" I hear. Really didn't think I would hear a difference with a microphone recording in a room, but not sure, seems to be something there.
To me it sounded the same listening on my onkyo amp and sony speakers it sounds great though and it is now going to be more reliable ,looks and sounds fantastic .
Usually, a restored version of any receiver or amplifier would sound much better, but it all depends on how bad those caps and transistors were to begin with. Try the Sansui G series receivers, in my opinion those sound much better than any other vintage receiver.
im not listening on great speakers here so couldnt really tell, but i would assume its more obvious in person. also need burn in factor. theres a lot of nuance in sound that doesnt get picked up when recorded like this, then compressed on youtube, then spit out my pc speakers
You are using similar capacitors, equivalent transistors and why will it sound different? The only difference could be noise floor if at all the transistors and capacitors would produce.
Having changed all those capacitors and it sounds the same is a gain. The sound may be better but we can't tell over RUclips and as we know, it will last and sound good for another 40 years. Marantz used good capacitors. I have a NAD receiver that had a great reputation for a value amplifiers and receivers when new, but, the sound of this receiver was unlistenable. I replaced the big capacitors and that made an improvement. This is a reason why Marantz cost more. I have a SR2000 (I know, it is not from the best era in Marantz) in my living room that is original and sounding good. If I can get the NAD sounding good enough, I will temporarily use the NAD so that I can "restore" the Marantz. By the way, the one issue that the SR2000 has is that 2 of the three meters is not working. Do you have any equipment coming up that will need the meter to be put back on it's jewels?
I agree with AH-Fit-It. I couldn't detect any difference on headphones or through the HT system in the living room. It is probably due to the RUclips compression algorithm buggering the sound up as it usually does. :( However to me it sounded distorted especially in the midrange and the treble. Bass a but muddy as well. Admittedly the the receiver is a basic lower cost model in the Marantz range at the time, but somehow I feel that there is something wrong with the sound in both the before and after takes. I know there are a lot of audiophiles that believe their ears tell them everything they need to know about audio but a few tests for frequency response, power output, harmonic distortion, intermodulation distortion and noise are IME quite telling when something doesn't sound right. I think AH should hook it up the the Magnapans and take a serious listen.
What do you think, you like it? Now maybe you will understand that you've ruined that pretty good sound. Some of the original voiceing remains...but midbass sounstage is gone, mid's yelling at you, mid-hi region moved up....entire sound moved up....and it's CRISPY, and with modern touch. Kinda FLAT sound as well. Before restoration, you can listen it for hours, now after half an hour you'll get tired. Great job!
I didn't detect any significant difference because IMHO the before and after sounded pretty crappy and somewhat distorted to my ears (and not listening through some crappy laptop speakers either). I think there's something else wrong with the receiver that got overlooked. Sadly newbies often are sucked into the recap everything hype propaganda that somehow seems to plague the audiophile forums and some RUclips channels. What gets me is a receiver or amp that's been working for 40 years without trouble somehow needs to have all the electrolytic capacitors and all the semiconductors replaced. Why? So someone can replace capacitors in the power supply with some "audio grade" capacitors with a 1000 hours expected lifetime as was done on one of the videos? LOL I wonder who comes up with this crap? Clearly someone who failed elementary school arithmetic. 1000 hours MTBF = less than a year's worth of listening if used an average of 4 hours per day. And as for changing rectifier diodes in a fully functional power supply - I just have to ask why?
@@alanrutlidge4767 "PLAGUE" you're right! I'm not a hater or something....but it hurts to see this. Those vintage amplifiers/receivers/decks/cd players....are harder and harder to find. Germany consider those as "toxic waste" and destroy them in large amounts. It's sad!
Restored Ambient is definitely better, but why does the wire (hanging off the table) move around? Is the cat contributing? As for "Rock," couldn't listen to it. I hate metal. (Character flaw.)
Don't you have anything better to do? You're good in electronics. Why vintage? Try repairing modern electronics....ultamega xxxxkkk fancy ghizmo's, like TV's, Playstations,Hometheaters. Everybody get's happyer...young and old ones together. I just don't understand how it's sounds the same for you. Try listen and compare this on big FAST detalied NOT before mid 70" speakers....like Pioneer HPM series, or speakers OVER 91-93 db's sensivity and maybe you will hear those diferences. Speakers evolved after '80. Or try finding an experienced person to teach you about sound. But not a DJ! :)) At least do that simple test: Listen 2215B for 20-30 minutes, and you will get tired, bored, nervous....why? This was a big problem for us too, you know? We don't get any pleasure listen music anymore. Because it sounds like crapp! Shitty music/recordings/compresion/loudness war/sources/modern amlpifiers/speakers....cap's with SALT WATER electrolite (pollution regulations)...that's why! Please don't get me wrong...we are more than happy to have you, but....
Well if it's A+ gear, then it's worth at least some of the hype, eh? There's no denying they sound & look great. If anything, they're all over priced, rather than over hyped.. There's still 1000's of all these receivers out there, still working. There's really no need for people to be charging what they are nowadays. Restored receivers will obviously cost more, but for folks to charge 1000's of $ for something unrestored is a bit dirty IMHO.
Nice to see someone from the young generation get into electronic repair, its a dying breed. Good luck to you!
Well companies design single use product, so no point anymore.
Agreed.
There's a reason why Marantz is a highly sought after receiver. You just proved why. Great informative video. Keep em coming.
Stunning transformation, excellent work

I have listened a few times and believe that I can detect slightly better separation on the upgraded version. Nice job, love all your content
Great video- thanks-as a former audio salesman from the 70s good to see people appreciate the equipment
There is quite the difference, the restored amp has improved separation and far more clarity, before that it sounded muddy and a lot less urgent.
Same as I heard.

Very impressed with your practical knowledge which you are developing. These receivers are like lp’s becoming very collectible!

The gentleman is repairing the
Marantz stereo receiver.

Sounds so much better after being restored! Good job!
I noticed a huge difference.. The restored version sounded a helluva lot better than the unrestored. More clarity, detail and punch. Nice job dude! 👍
'clarity"....pfff!
2215 original sound is not "detailed", with "punch" and "clarity". Is round, deep, neutral, musical as well, with sweet hi region....and especially BALANCED!!!! Not with mid-hi in front of you and agressive! Now....it sounds like Technics entry level. :(

I love your video sir. I love professional people who do best jop
Man it sounded great like brand new.
Can you please feature how to restore a Sony FH80 stereo component, the crispness of the sound is gone. Thanks and Godspeed
I glued the tuning wheel with electronics cleaner on mine & dropped it off at the recycling center, any chance that's it ? Small world if so
My 2226B and 2250 are having channel imabalance volume issues, very noticeable on low volume. Does Recapping fix that?
I too like the Loudness button on my Marantz. You mentioning it reminded me that I turned it off in October when I was watching a movie. Guess I don’t depend on it since it’s been off for four months but it is cool…despite all the “audiophiles” who say otherwise.
Hi I like to learn how to fix electronics too, i looking into college courses, like circuit analysis, what is a good starting point?
You see sound? Wow! I only hear sound. That is amazing.
@AH-Fix-It I agree with you entirely.

Hello do you do restoration's on the side?
Your philosophy on repairing audio gear is the same philosophy I have on repairing my cars! If it ain't broke don't... Wait. Nevermind. 😉
Hello. Do you think a marantz 2225 can power magenpan LRS speakers? Thank you.
It'll do it but it's not an ideal combo. You're much better off powering maggies with over 100 watts per channel.
Awesome. Thank you for the response.
Would love to have you do mine.
What about carbon composite resistors? They drift over time and what about transistors? They leak over time.
I wish I didn't know which one was before and after, my expectation bias is now engaged.
However, I think I hear more damping and less tubbiness to the bass in the after version. Tone sounds the same, just more taught and controlled. Would have liked to see tone bursts on a scope for objective evidence of what I "think" I hear.

Restored sounds tight
my marantz -2220-b sounds good - but would like to ger it like new want the job ??/ let me know ok wc
going to let me know -want to referbish my 2220-B marantz???
Thought the rock song sounded more clear after the restoration. The unrestored sounded a bit muddy.
Yes it is.
And that guy is right...abaut those KLH, move them away from walls
👍👍👍
Like your videos! But seriously, sound comparison via youtube? Pure nonsense!
I didn't hear a difference. Nice honoust video.
Maybe a 5% improvement 😏
