Hello from Meaford Ontario Canada : The reason the lights go out when switching from tuner to Aux is because the lamps can give off an rf signal and bleed into the other channels and it is done this way for audiophile purposes

True story.....I picked up a beautiful 7070 from a thrift for $20 about 5 years ago thinking it was a Realistic model. Threw it in my cart and when I got home I took a closer look and realized it was actually a Sansui! What was even more of a surprise was that it worked perfectly!

I'm guessing no-one mentioned 'be careful after replacing the fuses after biasing on 8080/9090's as the filter caps won't discharge on power off' lol. There's a trick to it - solder two leads to either side of a blown fuse for each channel and use those in place of the fuse to do the bias, bias, then power off, remove the amp board and use a fuse puller/pusher to pop the fuses back in. That way, it removes the danger of shorting the amp board/outputs when popping the fuse back in. The 9090 was one of the amps that hooked me directly up to our national grid (240v), was a fun afternoon that one.

Great video Aidan👍👍 Yep, dirty switches and old capacitors are the two biggest problems with vintage stereo receivers it seems. Nice balcony scene, definitely have a view and having furry helpers doesn't hurt. Thanks for the video and work, always interesting and fun. Enjoy!

Wonderful video!!! I have audio equipments since I was born in the early 50´s from valvular to transistorized. It is good to see youth like you caring audio. You give me Hope. I do love cats. Cheers from the coldest place on Earth, Patagonia, Argentina.

Wow, special effects and a diverse group of co workers to talk with. Nicely done Aidan, love the addition of the table to take advantage of your outdoor workshop extension.

I had a model 7070 and worked for 40 years

ohhh, funy to see how you manipulate those screws in a gobly table and if you drop one, will go down the deck and above! So fearless!!!

That receiver looks to have been well taken care of. I have a 9090db I recently restored and I think it sounds great. Thanks for the video

I loved this video because I have a Sansui 5050. My son found it on Craig's List for 75 dollars and it is in perfect, mint condition. I feel bad that you had to do so much to clean the pots because the 5050 took me no time at all. I took the cover off and there they were. I can vouch for the FM sensitivity too. I also have two feline co workers but only one ever gets involved with my repairs. LOL

love the outdoor class with the cool Professor

What a great view from the deck! Good to see the "supervisors" in the video again. Beautiful receiver. Thanks for putting another informative fix it video together. Always look forward to new ones.

I agree regarding the speaker terminals. What a cracking job. Well done.

Love sansui equipment... pretty well made.. great video as well. Thank you. ✌️❤️😁

It's nerve wracking seeing the loose hardware on that folding table! I use an old ice cube tray to keep hardware organized, and write a brief description of each cell's contents on a clipboard as I go.

Nice outdoor setting & lighting, but I'd be concerned about dropping small parts through the decking as they'd be gone forever! 🤔

Montana looks beautiful. Hi from Alberta.

Nice to see back again brother! I absolutely love the looks of that year Sansui Receivers. The first one I bought was a 7070 & then the addiction grew & went on up the ladder until I reached the 9090db which I've own 3 of. It's been fully restored & absolutely fabulous sounding.

Greetings, thank you for your teaching.

Great job! I have same receiver sitting for maybe 20 years. I loved the quality of it and you made me to think get it out of storage and check it. If you come across a power amp, that making cracking noise, please make a video.

I have a 8080 and just had it serviced half a year ago, runs very well but recently my aux switch went out. Probably go and get it serviced again. I also use a Sansui 2000X. Peace & love

Beautiful out there! Nice place to work.

Hey, I've got this old amplifier that I love. It's a Realistic AM/FM tuner compact stereo. The controls need to be cleaned because they're all sketchy, and the volume distorts when I turn it up too high. The FM tuner feels really loose too, but I don't really use it that much. I used it as an outdoor radio for a year, and it worked great, except for the junky speakers I had it hooked up to.

I like the 8080, better than the top dog 9090. It’s got a much more conservative appeal. And it’s 94W/ Ch are still very potent! A beautiful presentation.

When you put the positives in the middle it's better business for the company. They don't have to wait so long for people to decide to buy a new receiver. It's always the time to buy a new one when it goes up in smoke.

Long time viewer. I'd really like a video on the equipment and hookup you use for testing. Signal generator, Osc, etc. Thanks!!

nice video,. great view,. im gettin Shango vibes with the electronics outside,. i love ur kitties name,.lol

I would be a little nervous with a relatively heavy receiver or amplifier on a fairly flimsy plastic table, especially outside on a raised deck like that. Just having the screws roll around on the bare tabletop (instead of putting them in some container) seems like a bad idea too. The white tabletop and natural light does let you get some good thumbnail shots, but doing any serious or precise work out on the deck wouldn't be my first choice.

Definitely gonna be a fun one

Thanks!

Earned a sub with that one. Nicely done.

Crows are vindictive, Aiden...If you piss them off, they will retaliate! Lol

I think the reason to stick capacitor with the relay is to reduce vibrations. As I can see, the capacitor is a few millimeters above the board.

many people think that with a little deoxit, the controls are good when they stop being noisy but if you have a distortion analyzer many times you can see the amount of distortion a dirty but "noise free" switch adds. i hate doing it but switches need to be disassembled to be properly cleaned. it's very stressful. you may not even notice the distortion with your typical vintage unit but something like an sx3900 with it's low distortion, it's important to clean those switches. even then, you may or may not hear it but it may be measurable. sometimes i get pretty anal with my restos, other times, notsomuch.

love your vids the cat is the wife right

I don't remember the details, but there's a really easy mod to have the tuner dial lights on all the time, which just requires moving a pin to a different slot in one of those plastic headers, no soldering required.

Had an issue on a 80s JVC that was going into protection due to oxidation on a switch causing a short.

I am sure you have video where you show exactly where you spray the Deoxit on both types of switches? Wanted to make sure I do it right. Thanks in advance.

Very nice job. What are those speakers you have again?

Hi, Like the videos, what and where did you get that color chart you're referencing for values?

Nice video but it would have been nice to see how you clean a push button control instead of speeding through it. Cut out some of the cat footage if you’re concerned about video length.

Do you use a Lazy Susan ?

So have you dropped anything off the table and down through the deck to never find it again? 😮

😸👍

Hello SADE

Oh snap! LOL

No Pad protecting Receiver from hard, abrasive table top?

You just got over 20 watts at 15Khz and you just ignore it? I think your Fluke is the problem, most multimeters don't go that high. Buy a modern oscilloscope that shows the correct value and problem solved. Greetings from the Netherlands.
