I restore old stereo systems and build some furniture. I offer repair and customization services for amplifiers, receivers, and turntables. I accept repairs that include customizations (new veneer or wood case, crossover upgrades, full amplifier/receiver rebuilds etc). My shop minimum charge is currently $300 + shipping which means I will do a minimum $300 of work to whatever is sent to me. We can discuss what specific repairs that would include. If you've got a project that meets these standards, email me: shuksanaudio@gmail.com
It's so EASY to repair: Yamaha CR 450
eBay sale 👉 www.ebay.com/itm/387155095617
I picked up this Yamaha CR 450 a few months ago and was told the meter lamp was burnt out and the left channel had distortion. The CR-450 was released in 1976 as a replacement for the CR-400 which was having issues powering the lower impedance power hungry speakers that were being released in the US. They doubled the output transistors and power handling while also beefing up the power supply and removing the current limiting circuit. It can produce nearly double the 32 watt per channel output at 8 ohms to a 4 ohm speaker. It sounds very warm compared to the rest of Yamaha’s 70’s lineup and is one of my favorite looking so I was very excited to get...

Restoring A Mid Century Classic: The Advent 5012
Просмотров 2,3 тыс.2 месяца назад
The large Advent loudspeaker was released in 1968, designed by legendary sound engineer Henry Kloss. His goal was to create a budget friendly speaker that could compete with models that were far more expensive. The original Large Advent (OLA) went on to develop a cult following and garnered attention for it's incredible sound when stacked two pairs high. In the 70's the speaker was updated to t...

Good job 👍
Good job well done. 👏
I worked for Advent during the late 70s as a district sales manager in the Southeastern U.S. It's pretty rare to see the 5012 and 5002, but, as I remember, the "Direct Report" tweeter (Direct radiating, parabolic dome, optimum range tweeter) was the big new feature! Unfortunately, as your demo showed, a lot of people felt that the new tweeter was not an improvement over the original Advent tweeter. Most consumers felt that the new tweeter sounded "muted" compared to the original product. You said you matched the levels between your Tannoy's and the 5012s at 1 Khz, but that can cause results similar to what you heard. Pink noise or even white noise might do a better job of letting you match levels to remove efficiency from the equation. Enjoyed the presentation!
안녕하십니까? 3번째 우퍼 스피커에는 배선이 연결 되지 않나요? 음을 효과적으로 들을수 있게 장착된 패시브 스피커 일까요? 매우 궁금합니다.
wow. the difference is drastic. the before sounds downright abrasive. i've got to dig up my old silver's and get to work!
Would be nice, next time, to hear a before and after sound check.
I bought a pair of 5012s pre-Jensen in Seattle at Pacific Stereo. I still run them on my main system and they have been re-foamed a couple times. Still my favorite pair of Large Advents that i will not part with. Great video and i love the restoration work you did on your set.
I have the 5002 I found local and they are in really good condition. Mine have cone tweeters instead of domes but they still sound good. Edit: whoops my speakers are the 2002 model. That explains the cone tweeters.
Beautiful, gorgeous piece of gear. But I would stack my Pioneer SX-1980 up against it, any day! lol
Why replace the resistor? Was it burned out or something? I always thought resistors are like inductors... they pretty much never go bad. Did you change the resistance value to modify the tone? Thanks!
So glad you started this channel! I really enjoy your content. Those advent speakers are a gem. I use to have a pair with the fried egg tweeter.
G' day Matt, Just came across your channel mate & of course subscribed, Very good tutorial & style in your vids, Great explanation on A vs B as I first thought B was better as it sounds louder, Then after your comments, A sonically was so much superior, look forward 2 when U make the kit with all of the parts that will be cheaper. Cheers!
Truly an outstanding video. It deserves way more views than it has. But I almost passed when I first saw your appearance, because I thought "amatuer". A haircut and a shave would go a long way in promoting your channel. Sorry... that's harsh, but appearance goes a long way if one is trying to portray seriousness in their message. You could have hundreds of k's views on a video of this quality. Take that extra step.
Thank you! I'm glad you liked the video. I don't care if you don't like my appearance. I make videos to enjoy them and I am not an expert. I am, however, always learning and teaching what I know. If people can't see past what I want to look like, that's their problem.
I have been an electronic repair technician for over 30 years and your attention to detail and technique mirrors my own and it is a pleasure to watch you work.
Amazing! I'm glad to hear that you see those things in my work. I try to do each step the best I know how to do it and take my time. I appreciate you watching :)
You have good taste.
Thanks Brian!
Fono not fawno. And i recently had one of those fishers i got thrown in for free and they have an STK and are decent. I believe that 831 is 45 watts per channel but they dont like anything less than 8 ohms.
Sure. Nice, this one actually uses discrete components. Big old heatsink on the back. Pumps out around 100WPC and I use it in my shop. Big fan!
Sansui 5050 for 50$? Thats a stupid steal!
It was $80 but yes, still a very good deal!
Fawno? Fono. Phono section.
Someone's picky
Ask if they got anything in the back that hasn’t come out yet every time you go there
I do that sometimes, they usually don't. Sometimes you get good stuff though!
A is a good a guess as any when given A or B on a youtube listen test..
50/50 chance
I especially after you “took off the wood case” don’t trust you doing anything to it or any other things you manipulate in some sort of fashion or another…..😂😅
I have no idea what you're trying to say
ruclips.net/video/AJHzhSDgLlY/видео.htmlsi=ISOC9-iGtTRlkKEN If the channels start intermittently start cutting in and out 95% chance its corrosion on speaker relays. Factory relays are not sealed, buy sealed relay replacements and install. The cost between sealed and not sealed relays really begs the question why they didn’t spend the extra few cents. These NADs and Protons would have one of the best histories of reliability in all of hifi. Instead everyone thinks their channels eventually go out when its just stupid relay contacts.
That was never the problem
Wow. 333.Rick
Great work man. Funnily enough I had a similar fault on the same model and it was an open resistor as well in the same area. Weird how they fail like that, guess its age and the oddities of electronics 😁
Thank you! That is wild! Maybe the used some cheapo resistors on these. Always fun tracking down a new issue haha
Granted my ears are probably terrible, but I heard absolutely, totally no difference.
A is the tubes but B still sounds better 😂
You need to crank it up to enjoy it 😉
Haha lol yea listening loud is always a good time
Hi Sir, I saw your ad for the CR-620. I have that coming to my workbench in a few weeks and wondered if I can get the replacement component list from you?
Hey there, I replied to your comment on Facebook I believe. I do not have a parts list as I keep many parts in stock and can pull and replace each component. I did give some tips on transistor replacement though! These are my tips for the CR 620: "Replace all of the darker blue Taicon capacitors. They're almost always 50%+ out of spec. If yours is not made in Japan, almost all of the caps will be Taicon. The preamp is always full of bad caps and transistors. Replace them all. You will need a dozen KSA1015 to replace the 2SA844 and a few toshiba TTA004 and TTB004 in the amplifier. The 1S1885 diodes in the power supply and protect circuit can be replaced with 1N4002. You’ll also need a couple of 1N4148. There are lots of great threads on recapping the 620 on audiokarma."
Is this basically the same for KG 5.2? I have a speaker that the high end is just dead. I bought replacement drivers with hopes this is it, however I would appreciate a parts list to replace all the components on the board.
Thanks for watching! The crossover is different. You can just pull the board and look at the components on it. Easiest way to get a parts list together. You should only really need to replace the electrolytic cap and the tweeter protection components since the other caps don't tend to age poorly.
EVery sound you hear is coming through the solid state amp of your computer. Since SS amps are essentially perfect, if there is any kind of difference, the valve amp is causing distortion.
Yes, but SS amps are not perfect haha. It depends entirely on the circuit design of the amp.
Nice work!
B is Harman Kardon
I have two sets of Advents. The smaller bookshelf & bigger from either the late 60's or early 70's. The bigger ones need woofers worked on & repaired. They still play but sound bad. The little ones really rock.
Nice! Yes, I wouldn't recommend listening to them if the foams are rotting. It will damage the voice coils beyond repair. Thanks for watching!
Those tweeters are very much irreplaceable. Their lower range is much lower than the usual tweeter, 350 or 700hz, I forget off the top of my head. Maybe the Optimus 1B was 350hz. Nothing in the parts express catalog at the time I had them other than the large diaphragm tweeters had sufficient range.
The lower driver is actually a mid range. It takes over around 700-800hz up to 4khz or so then the tweeter comes in. They look the same on the front but are labeled differently on the back. Still pretty impressive that the mid driver can go so low with such a small dome.
I just got one of these SR-1000’s, too! Your detailed restoration is helping me a lot!! Thank you 👌
Awesome! I'm glad to hear it!
A. all day
A is tube and b is solid
Will those cleaning techniques work on the insides of my lungs?!
😅
So, you did the test pre and post modification, or are we listening to two different speakers?
Same speaker, before and after :)
@@Shuksanaudio excellent. A measurement mic and fft software would be a good addition to help testing
❤❤❤❤❤
NICE!!!👍✌️❤️🎼🎵🎶🎵🎶🎵🎶🎵🎶✨
I'm going to try the Magic Eraser method. As for the circuit boards, I usually use CRC contact cleaner. You can buy a couple of cans of it and just absolutely spray everything down and soak it and it will not hurt anything. It will usually wash most of the tar off, but you may have to do some scrubbing with a toothbrush. You will want to avoid spraying the if and RF cans of the tuner, as well as the variable capacitor.
Good info Scott! I have some of the CRC cleaner and a tooth brush. I will give that a go.
So on my Akai AA-1050 Aplifier the case is just cheap mdf with a plastic veneer on it to make it look like real wood so I used brake cleaner to clean it and it worked perfectly and for the rest I got it professionally serviced and cleaned
Wow, brake clean seems really excessive but if it works, it works Thanks for watching!
I literally open my gear up once a month to clean and dust it. I bought it off a client from work who always had a huge Cuban cigar in his mouth. The Toshiba preamp and power amp looked like it had a champagne finish on it but after cleaning it the brushed aluminum finish popped .
Wow! That is some diligence! I bet that was a satisfying thing to wipe away all of the tar! Thanks for watching!
@@Shuksanaudio its always satisfying seeing projects come out nicely even if it’s just cleaning. Keeping it clean is the easiest thing once you’ve done the hard part.
Good Job
