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

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!

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 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 old Marantz And Sansui's. I still use a Quad 7500A I'd say 60% of the people I've had over here to listen to Rap, Funk, Rock or Classic like the Quad over their modern 5.1 or 7.1 Surround systems. But it took me ages to find the right mix of front to back speaker combo's to bring out every nuance in sound. So I get why people pass them up. Without proper placement and speaker matching the sound is only marginally better. But put in some work and it's very notably better..... QS Synthesized or QS Surround (found only on the 7500A or 9001 Quads) it's an very active surround sound. I'll never go back to Stereo!

I’m working on an old pioneer elite vsx 39tx Stand by on and I hear the relay clicks but the amp won’t turn on. Where should I start. I work on guitar amps primarily . Thank you. Really enjoy your videos.

@GlennBerrySQL 3 ай бұрын

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.

@josephlalock8378 2 ай бұрын

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.

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.

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.

True! The Fluke 117 is specified only up to 1kHz with True RMS. Even with his old scope he could measure it much more precisely.

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.

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.

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.

@AmirAmir-ue6ld 3 ай бұрын

@jacobrodgers2700 3 ай бұрын

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.
