1969 Magnavox AstroSonic Console Stereo restoration Part 1

- I take a look at a Magnavox AstroSonic console stereo straight out of your grandparent's rumpus room. Fixing a dead channel, dirty controls, old caps, and a good look under the hood it's all there!
The capacitors I ordered: 1drv.ms/u/s!AgRy1tCE6lTdgbUJE...

watching this video is already starting to tell me where my problems could be, i'll also watch part 2 so it tells me everything
Just a tip on Magnavox stepped tone controls. The first position is cut, next is flat, next is boost and the 4th is more boost.
Thank you very much Rob! You just solved a mystery for me that may have ended up in a broken plastic faceplate. Mine is a later model like the one you have and was hard to find instruction for some reason. Great video
Thanks for posting! My parents had a similar console when I was still in single digits; was never tall enough to see the treasure inside though. This unit looks to have survived in very good condition for a 1969 production date...oh the stories it could tell! Looking forward to the following episodes! Thanks again for your time!
Funny, I kept scratching my head as to how to remove those inverted nuts. Finally made my own tool like you did, but didn’t need to weld anything. I’ll go get the link and send it to you.
I saw someone else make their own removal tool as well. There is one for this purpose, but it's about $65.
That tool is still around. Those are called Palnuts. Xcelite sold all three sizes for their 99 series handle. 99-716, 99-816, and 99-916. They are getting hard to find. I have been looking for a set for a long time.
Great job at making a good copy of one yourself.
It's a beautiful stereo sound system.
you may be able to put a different changer in that if you can't fix it but i think it can be fixed
Luego de reparado lo pone a la venta!!!
i have receiver with a 231 chassis but its attached to a piece of wood and the receiver has a dead channel?do you know anyone who might be able to get the wood part if you can't
I have a 1964 Magnavox that needs restoring, including the turntable tone arm stylist and open-reel tape deck. I don't know anyone in my area that does this. I live in Vero Beach, FL. What or who would you recommend?
does the bass control have an intermittent contact?
did you check for cold solder joints?
Awesome video. My wife just bought a 1969 AstroSonic model 1P3822. It looks fabulous, the record player works, and the speakers (boxed in stryofoam) work great. However, she didn't realize that one side had no volume. I pulled the board and found a blown resistor and possibly a couple output transistors replaced. Also, the internal/external/both switch had been broken and wired back together. It needs someone to repair it but we have no idea who or where to take it. We live near Little Rock, Arkansas. Any pointers or is there anywhere we can ship the board to be repaired?
Nate, I don't really know anyone that does this type of repair. It would be a hard way to make a living, I do it as a hobby. If you leave me your email we could chat further.
i found the chassis no. but i can't find a manual, do you where i can get one?
Very interesting, as an expert in this, what do you think about Motorola? We had one of their consoles back in the 60s I think it had a very good quality.
are those power transistors silicone or germanium?
i bought a receiver that was made about the same time but the wires were cut and the seller doesn't have a chassis no. for it, can you tell me the chassis number on that?
I’ve got the same unit. I have some distortion at low volume on one channel. I was just going to recap it but can’t find the exact capacitors. Do you suppose it’s safe to use 470uf in place of the 500uf and 220uf in place of the 200uf and 250uf?
I do another Astro Sonic video that is 3 parts. On the first part I include a link to the caps I used. Most of the time ok to use higher capacitance as long as the voltage rating is good
Interesting video. My dad had a consul similar to that around probably 1967 I think. I have a question for you. I have a Kenwood KR-7070 that I have had for a long time. I just started noticing something yesterday. I was listening to the stereo and I got a phone call so I turn the volume down all the way, when I did I noticed static was coming out of my left speaker predominately and just a little on the right. I turned it off and I came back about one hour later and turned it on, and then it was quiet. But 10 minutes later, I turned the volume all the way down, and I could hear the static, kind of like a rushing noise coming through of the left channel and a little on the right. Could that be a resistor going out or a capacitor? Any idea? Thanks for your time. By the way, do you take in outside work for repair?
Some of the videos (xraytony especially) attribute that to flaky low power transistors in the front end of the amplifier. I just do this for fun and I've got a ton of other stuff to do so I can't help you out on the repair. Good luck, I really like those Kenwoods!
@@RobsFixitShop thanks a lot for your input. I noticed something after posting my original comment. It seems to be intermittent. When I turned it on about two hours later, I didn’t hear any noise. Until about five minutes later that’s when I could hear the rushing noise of static. So whatever it is, it doesn’t happen until after about five minutes or so when it warms up. Still sound like resistors?
I don't know if you are still monitoring comments for this video. But great video. One question though where were you able to get the electronic schematic for the 1969. Currently just got a 1969 myself and going to have to make it work
I got the Service Manual here: theschematicman.com/about.htm
I would share it but it has a copyright line on each page. Good luck on your restoration!

Hey Rob. I have this SAME exact model. Could you please tell me the model number of this and where I might be able to get the SIMS service manual? Pretty please? :)
the model number was 22008 and was marked on the chassis. I got the Magnavox service manual (Which I like better than the SAMS) from: antiqueradioschematics.org/contact.htm Have fun!
PAL NUTS are a pain in the drain!
No kidding!
Here is the link : ruclips.net/video/2zflvzbOYwc/видео.html
That looks like a great solution, much better than mine where I had to grind it down to get it to fit
@@RobsFixitShop I did too, you got to do what you need to do! Whatever works. Thanks for watching.
