It is alright. Wish it was mine. I have an equally nice receiver, perhaps even nicer. A sansui 9090Db with Dolby FM! That is a rare beast, that goes for about 1,300.00 these days on the used market. I will overhaul it some day. I'm putting it off as I don't want a hernia lifting the beast! (that and the fact that it works fine except for noisy switches and controls)

My dad, now 80, had an old receiver sitting at home - one day it stopped working so he replaced it with newer tech, but couldn't bring himself to toss it, so it just sat, for years. I found it and using videos like these was able to repair it... lucky me, a G9000 in mint shape 😁. Turns out he was a Sansui dealer back in the day. My aunt has a 9090 that I hope will find its way to me at some point also.

+Donald Ellett My McIntosh is over 50 and it still works. Has developed an intermittent popping sound in 1 channel, I guess one of the old tubes is starting to go, or a capacitor is going south. One of these days I will put it up on the bench. Not a super high priority right now as I am not using it. I have a modern tube amp that sounds superior for music to the old one just due to better, higher tolerance resistors and capacitors, so I use that amp (A Yaquin FYI) for my CD player and turn table.

Nice fix! Love this older kit - fully agree nothing is like it these days. Cheers, John

Vintage Toshiba units are very under rated. I have two that are practically bullet proof.

Another cool repair! It would've taken me hours before I would be going after that resistor, I just always assume they will be fine.

+Koffi Banan That resistor was the second part I tested after removing the board. It wasn't just luck either, as soon as I determined that the repay coil was not open (as that happens) I checked the transistor array (that black part that looked like a SIP IC, but what makes it different it that it is only a transistor array without internal resistors and other circuitry) for shorts. None found I started looking at the support componets.

I could have used your knowledge back when I worked in consumer electronics. You are the best!

Beautiefull receiver just a pleasure to watch and listen..

Nice repair, what an optimist, reassembling it almost completely before testing. Thanks

A fine presentation there. It seems sometimes high value carbon film resistors go much higher in value after much use.. In the days of tubes, there may be a 1 Megohm resistor going to, say, 50 Megohm, which has a significant effect.. With faults of this type, you have the benefit of reading the color code to ascertain the correct value.. I like the idea of a link from the 'tone and volume' stage to the power stage... The Akai AM UO3 stereo amplifier has this too... I use it to connect a remote control Digital radio, with Bluetooth directly to the power stage...

Nice troubleshooting. And the unit itself is a beast. That toroidal and the caps are huge. Love the modularity.

Been trying to buy that unit for years from its owner. He got it for free but won't sell, and the kicker is he's definitely one here so he can't even hear stereo.

I have seen that the amplifier still had the original "Marcon" filter capacitors that are working on borrowed time. And yes, all audio equipment were made very good back then. Especially the Sansui, Pioneer, and Marantz brands in my opinion and in that order were the best made in Japan.

I think these were made by Technics and those were made by Panasonic. Kinda strange the way they had a brand that made many different units for other companies.

+ElfNet Gaming When I was in the business many would have called me a crook for charging 125 to re-solder the ground connections in all those Sony tuners., however the good offset the bad. There were many times when a tough dog would take hours and hours. I remember struggling with a Pioneer 70" projection set for about 9 hours the first time to find 1 cracked solder connection buried deep in the chassis. Now there is not way I could charge the customer for 9 hours @ 80.00 an hour. That would have been 720.00 in labour. So they were charged 150 for the repair, as was the next 30 or 40 of those sets I saw in the next year an a half that they were all failing. It only took 15 minutes to fix the fault once it was identified. Same went for all those Sony tuner failures. They took about 15 minutes to fix, but in the early days, before the fault was figured out, it was replace the tuner at a cost of 110 for the part and 80 for the labour.I even had one smart ass customer that wanted a break down on the cost because he got a bill for 150 to fix his TV. He went to the media, and they tried to set me up with a simple blown fuse. Of course the blown fuse trouble generated a 29.00 labour charge, the shop minimum. But when asked about the 150.00 for a broken solder connection, it was broken down as follows.Re-solder broken solder connection $5.00. Knowing which connection to reflow $145.00! There was no comeback for that. Also back when I made a living repairing electronics I did not share my knowledge with anyone, especially the guys that worked in the shop with me.Electronic service engineers, which is what we technically were, a technician would be what I would call my assistants, the guy that took the back off, and did minor things like replace belts and clean controls. I was working at an engineers capacity. I was the one that could read, and understand the schematic, and knew how the circuit worked. That is what put food on the table, and I wasn't about to show some noob the tricks of the trade, that had taken me so many years to learn. So we had to charge enough to earn a comfortable living, and pay the expenses of running a retail establishment.I am not in the business now, at least not as my main source of income. I work in a totally different industry now, but I still live in the same community that the shop was in, so many people know me, and still bring me stuff to fix.The purpose of these videos is to hopefully get people interested in this field, as they certainly don't teach it in school anymore, and the post secondary courses just don't exist anymore. At least they don't for consumer electronics.The little bit of beer money I make from KZread doesn't hurt either.

That is a rip off.The shop I used to work for made a killing from monster cables, and the sales dept would convince people that a 150.00 cable that cost 14.00 dealer cost was going to make a difference in picture quality.I locked horns with the owner by telling a customer that their 3,500.00 DV cameras needed a new 600.00 digital board because the DV connector was ripped off the board from using one of those stiff monster cables as opposed to the 40.00 Sony cable. The customer cam storming in demanding the shop refund hos 150.00 for the cable and fix the camera for free. The boss was not happy with me for telling the truth, as he made a killing selling those stiff cables. Had a bunch of TVs get their HDMI connectors snapped off by those stiff boutique cables too. To this day people get ripped off on headphones, batteries and connection cables.

Those capacitors are huge! Did they require discharging? A great video and very informative.

+DLiberator78 Those caps can hold a good charge, but the voltage is not that high. 45 - 55 volts each, so 90-110 volta DC potential difference between the + and - rails. Saying that, they store enough energy to blow the tip off a screw driver if you discharge them with a dead short. They do discharge relatively quickly though after power is shut off, because the circuits are still powered by them, and this will discharge them within a few seconds. If they were isolated from the load by a relay that cut power to the circuit when AC was removed they would hold their charge for quite awhile, but that isn't the case. The relays cut the speakers, and let the caps discharge through the circuitry. That is the reason for the speaker relays, so that as the caps discharge there wouldn't be DC voltage sent to the speakers caused by voltage imbalance between the + and - supplies as the power supplies discharged.

I had a Toshiba beta vcr, very nice. I used to wonder if Sanyo was Toshiba's cheap line? Either Sanyo or Toshiba made stuff for Fisher in the 80s. I've liked all the MIJ Toshiba stuff I've had through the years, including a very nice turntable and I still have a pair of 12" 3 way speaker systems. My led flat screen is T, no problems for many years. I think T was rebadged for some of Sears too. So you probably had to charge the customer at least one hour for a 2 cent resistor! My brother paid a tech about 300$ to recap and an IC chip in his T 36 CRT TV set. He said it was well worth it to him, although it was about 40$ for parts, that know how and labor was worthwhile to him, he really likes that 10+ year old TV set that weighs about 300#. I have a more basic model 36" T CRT set that I got at a junk store very cheap, fantastik TV.

Get a domestic made appliance, or electronic equipment, and there is a sence of pride by the well paid workers that built it, and they put in quality well made parts. You pay a premium for this though. Then there is the churn out 10,000 units a day from some mega factory over in China, where everything is plastic, and you are lucky if it lasts past the warranty. Who is to blame? We are. We demanded cheaper products, and manufactures looking to keep their profit margin just off shored the production to the land of cheap labour, and we end up with shoddy products.

zorroon milkavitch Actually I went to bcit and studied television production. I had worked at a TV shop when I was in school. I knew owner from when I was about 10. He had been a radar engineer during ww2. I went to the shop for about 3 hours every day from about grade 7 through to 12 and learned enough to take the journeyman red seal challenge test which I passed easily. I then finished school and decided I didn't want to work on electronics and wanted to get into TV. Studied that but there was no steady work local. Worked for a community station, did an internship and summer relief work. Saw an ad for Sony looking for junior technicians. Applied for the job got it. Sony put me through the VCR factory training course. Sure it was betamax but same principle just different mechanism. Did that for a year and they wanted me to relocate to other side of country. Left Sony and ended up in a small warranty depot. Over the 20 years I was there took constant manufacture courses for new tech. I forget how many buy between 50 and 100 I would think. 5 or 6 courses in classroom a year. I filmed one of them and put it on the channel. A super beta course. That day I filmed was the theory day. The balance of the week it was hands on taking the machines apart and finding planted faults that the instructor put in. I left the electronics service business in 2003 and retrained in the telecom industry where I work today. A few years ago I got the idea to start the KZread channel. I had, during the time I worked in the repair business started a video production company and produced hundreds of high end multi camera shots of weddings, live performances, theater, TV commercial and infomercial and corporate videos. When my business partner died in 2007 I wound down the production business. Then I got the idea for the KZread channel and put my production skills back to work, except now I do everything myself. I used to just be the guy running the camera and editor. I hired the talent, voice over talent, additional camera people ext. Now it is just me. Instructor, camera operator, editor and voice over.

@@Budro4764 yes I know. There are many that I have hit the mute button on so they can't comment anymore. Some come back with different names but it is easy to figure them out and I and my moderators that patrol the comments have itchy ban fingers. Frost hairs found out that quick when he started calling me a liar when he confronted me about deleting his post. It was actually my moderators that nuked his post and many others in the old films from the 50s. There were some comments that were racist and offensive and they were deleted. Then I get harassed as to why the comments were deleted. Thing is I have 2 moderators on my channel and they are actually faster then me at removing comments, but as the channel owner I am the one lined up in the crosshairs when someone gets upset. I ignore em all these days.

@@zloben9000 Assuming that the meter isn't damaged, but in this case the meter is damaged. There is a piece of metal inside the meter stuck to the magnet and jamming the voice coil on the meter, so it won't go down all the way. I wasn't going to take the meter apart. The owned didn't care and wasn't aout to pay to replace the meter or attempt to fix it. Guess what, most people don't care about little things like that. The guy that owns this uses it in his garage!

Great video. I sent you a comment on my Sony STRDG510 reciever. Please answer if you can thanks. Gio.

thank you for this...

I have an amplifier that when you turn it on there’s no sound from the right channel. You have to wait for about one minute for the sound to slowly come up from that channel. What could be wrong ?

Intermittent faults are the most difficult to troubleshoot as you never know if you solved it. I walk away from intermittent faults because I don't want to get married to it.

I do not know if you have the knowledge that people advance the introduction because it is always the same and people, like me, want to go direct to the subject without to waste time with introductions

+Benjamin “Ozias” Esposti This is just for those that download the entire video and share it.If someone re-edits it then my intro is gone. I burned my copyright logo on my video "a week in the park" right onto the video, as that one is one that would be more susceptible to theft.I recently had youtube pull a video for copyright infringement. It was a commercial video I shot in 1999, and another production company took my footage and made their own video for the same product (the company was sold, and the new owner figured he could take the footage I shot and use it for his own video) That was 2004 when they "stole" my video. I was only made aware of it when the guy that did the voice over work for me sent me a link to it as he thought I had posted it. I saw it and went WOW, someone stole my work. I then went and found the original DV tape I had it edited on, and uploaded the original, highlighting the infringing portion and fired off a claim with youtube, and the infringers video was promptly taken down, and the uploader received a copyright strike. The thing is he (or the production company that re-edited it) probably didn't know they broke the law, but I never released my ownership of the footage that they stole. It was only by chance that I stumbled across this. I used to get ripped off all the time. Many years ago I marketed a DVD, and sold it on Ebay, and people would copy the disk, and resell it undercutting me by a dollar or 2 per copy.
