I liked the whole series, thanks for doing it! I’ve got the really big version of that Sony sitting on a shelf here, been meaning to dig it out and give it a spin for a while. I forget the model number but it’s 70 or 75 wpc and it weighs a ton. Got it back in the early days of Craigslist when you could buy things like that for $100-150 bucks.
Nice little receiver... get your wife a nice set of small speakers she will love it... I had similar issue, but i got a smart plug. Your rewire is much better for convenience.
One thing I wanted to mention from your last video. When you were turning the volume pot and it was showing a difference in output between the two channels and you had to adjust the balance in order to get them even. Then you changed the sine wave frequency going into the Sony and the difference in the channels was even greater. You were blaming it on the volume pot, but the volume pot isn’t frequency dependent. Try it at 100 hz and then 10,000 hz without touching the balance and see if the differences are the same, they won’t be. You have a channel with frequency rolloff likely due to faulty caps.
Speaker sounds 'right' to me. People in the comments saying otherwise, but this is pretty typical and period correct sounding for an average Hi Fi unit of the day. A lot of people don't understand also how far speaker technology has adapted and changed and playing certain modern music on old Hi Fi units can give unsatisfying sound. There are so many more bottom end and top end frequencies that are now more audible in modern recordings that trying to push those into older speakers that weren't designed for it can lead to 'distortion' or a 'fluffy' sound especially once you start turning up the volume. They certainly weren't designed with 'digital' in mind. Best to hookup an old tape or a turntable, or utilize the lovely radio, and really enjoy it for what it is.
Aidan- using a different approach and additional characters made this interesting to watch. 2 for one by making your partner happy and getting something off your bench.
I love the Sony equipment from this time period. I have a complete 4 channel (quadraphonic) setup that I bought new, that with some tlc and serviceing over the years works fabulously and sounds great!
I'm going to do the same thing with the Bluetooth receiver that I use for my Pioneer SX999, I do believe my receiver has a switched outlet in the rear panel. I may make an adapter cord that has a switch that I can route to the front so I can turn the Bluetooth off, but still use the stereo (multiple phones are paired to the receiver)
Instead of playing another song, hook up a known to be good speaker and see how that sounds. Just a thought, & my 1st ever comment. I need to comment properly soon and tell you how much I appreciate your videos.
I was wondering from the last video if there was something wrong with the tone generator, but wasn't sure, but now we all know!, so you have to test the test equipment! Lol 😅
Hi Mr. Ah-Fix-It, sorry I did not get your name. I am your current subscriber. Somehow, you got me really interested in working on these things. I hope you can help me with a small question. I have a Sansei QR-6500 kept blowing fuse, so I gave up on it and left it sitting for awhile. I currently moved it out after watching many of your videos and decided to pull it out to see. I bought a Variac as you shown in one of your video. Run the amp up to about 30V. Then smoke coming out at one of the terminal of the transformer. The terminals (purple ones) was detached from the connectors. If you don't mind, can you tell me what was wrong with the components? Is it because of the filter capacitors failed before loading the voltage to the transformer. Thank you so much
I'm pretty sure that speaker was supposed to come with. some fucked up crossover device or something. I think it was part of an all in one style system. Maybe I'm describing it wrong, but I'm pretty sure I'm correct! I am setting up a system using speakers that I think are the same and am possibly going to just put cool 4 inch drivers in them or something and yes it's to setup in my girlfriends bedroom and she loves the way they look!
Can you help me come up with some drivers that will make that speaker kick ass???? I actually am lucky enough to have two of them! I bought her a Kenwood KA 305 that I'm getting fixed up to hook up for her :)
Love the channel. Keep up the good work. Glad to see that you are married. I thought you might be one of those nerds that hides out in the basement with his cats.
Inside is a bad idea, since this stuff produces a ton of digital noise. Better keep it as far away as possible if you like clean tuner reception and low noise floor.
Your frequency generator must not neccessarily be broken. I guess that this unit internally uses a triangle generator, the sinusoidal signal is then formed via a resistor-diode network and small peaks of the former triangle may remain. For audio purposes a wein brigde oscillator with low THD is a much better choice - or a pc soundcard or cellphone solution like you already used.
So get to work on the generator and make a cool video of that. Then test the Sony again and fix the problems if any... While you're at it, give her the two Sony speakers you got recently. Make her a happy wife. 😁
You be able to fix the faulty frequency generator? That is important to do so before you attempt a new project. So next video show us what you can do to fix the faulty frequency generator? Must be leaky capacitators lol
Whats with the click bait title? Should have called it "Fixing the issues from your comments" Your wife was clearly not annoyed at all. Also seems a waste of a nice unit if she is only going to use 1 speaker
I had a pair of old speakers from the 70s that didn't have much bass anymore and after checking, I found that the material used between the cones and the frame had hardened. I replaced the woofers and the speakers sounded good again. Maybe let your wife take that one for now, but keep looking for another one or maybe a pair that she can have instead. In the meantime, she has something to listen to.
@@jaygosch8705 A pair of new or reconed JBL Control One doesn't cost much, takes the same space as this single junker speaker and i'm sure, she'll love the sound of a pair of Control One. If they are available in the US, a pair of a mid sized model of 2way vintage Canton speakers is always a good choice too and even cheaper - at least in Germany. Never had to recone a Canton yet. They're sealed with good quality rubber. On JBL the foam seals last 10 years max. Every used JBL is broken. The sound for money is worth the repair though.
Sound good whut cind of muick does you wife likes justun beferhead ore laddy gaba ore does see like walk in thd park ore does see like metallica ore acdc rock ore cournty whut do you like mabby make a video on you cd and records some day thank you
Replacing a precision piece of test equipment with an app on your phone... love it!
Not precision just junk.

Prime directive - Keep the wife happy!! 😀 A shorty but a goodie. Thanks Aiden.
Instrumentation failure! Nice catch, good job!

I'd second that.
Nice job! Always enjoy watching your videos

Nice catch with the tone generator!
Test gear needs love sometimes too. Dirty switches and pots will introduce distortion in the signal. Hopefully it's a easy fix.

Hello, I have learned a lot from you, thank you very much.
Happy wife...You have a happy life! Lol
Nice.. A clean Machine..

Your wife sounds so cute You're lucky

Sounds like a new video for the signal generator, Aidan?

I’d love to know the artist and name of everyone’s favorite song.
Love the channel. Keep up the good work. Glad to see that you are married. I thought you might be one of those nerds that hides out in the basement with his cats.
That could be speaker buzz, but it could also be abysmal MP3 music mangling. You need to test it with a tone generator.
Will the Bluetooth be inside the cabinet?
No, it's plugged into the outlet

What is the name of the phone app tone generator? I didn't catch it.
PA Tone
Android only.
Why can't you give her two little speakers? LOL
yeah, it sounds like the voice coil is shot in that thing. a couple small bookshelf speakers would be a better solution. 👍
OOPS, Aiden?
Neat old Sony. The tuners on that series are suppose to be superb.
Edit: Funny how you mention the tuner. Must be true!
So get to work on the generator and make a cool video of that. Then test the Sony again and fix the problems if any... While you're at it, give her the two Sony speakers you got recently. Make her a happy wife. 😁
👍
Make a cool video trying to fix the tone generator.
Not a fan of Bluetooth for audio.

Get rid of her then!
Whats with the click bait title?
Should have called it "Fixing the issues from your comments"
Your wife was clearly not annoyed at all.
Also seems a waste of a nice unit if she is only going to use 1 speaker
Your wife is getting a Mono not a Stereo.
True 😅
And with not too good of a bass response too 🥲
