I picked up one of these (a slightly newer model I think with a different style cabinet) from a moving sale for 15 bucks when I was in highschool. Works great and I use it to listen to the radio and play my vinyls. Would love to tear it down and clean it up someday, but for the time being I don’t see any reason to mess with it. Great video!
Power on the Treble control instead of the Volume is typical for these Astrosonics. Also, it is normal for the tone arm to tap the edge of the record before it drops; this is how the record size is determined.
I have a similar system that I use which needs the radio cord replaced...along with general cleaning and checkup. Wish there were more people interested in repairing these, they are a piece of nostalgia I hope never goes away. The speakers on mine alone are amazing. Record player still working as well. Love my vinyl.
I'm picking up the same exact model this Friday! So anxious can't wait to play my records on it!!! I wonder how clear and loud the speakers are!!!!?!!?!!
@@Mrpachuko13 if it's the original four speakers and they are all working it will blow you out of the house! What I post is muted because of fb regulations. Actually in real time the windows are rattling! Good Luck and ENJOY!
Twenty-some years ago while browsing around at a local Salvation Army thrift shop, I saw a beautiful Magnavox like this one except it was the smaller unit (looks exactly the same except does not have the storage space on the left). I had one of the guys plug it in and sounded great. Radio and turntable worked perfectly. The manager told me that it had belonged to an elderly lady that had passed away and the heirs gave her furniture to SA. The cabinet was (and still is) in perfect condition, not a scratch or dent on it, and as of today still works great. I don't use it very often, but occasionally play some of my old LP's...still have all my original Beatles albums. I took the back panel off once to check out the wiring and tubes, and was very clean, there wasn't any dust or debris like the one you repaired. The needle for the turntable was in great condition, I don't think the lady used it that much. I did find someone on Ebay that sells needles for my model Magnavox so got several. The sound is great as of now, my unit apparently from what I've read on it has six speakers (front and back total). It also can definitely blast some noise when turned up. Anyway, I really love it...was a great buy for $25.00.
I've still got all my old Beatles records too! If it is tube based, you might want to replace the electrolytic capacitors because if,when, they get leaky they can reduce the life of your tubes. Although it is tough to mess with something that is working. It's an easy diy job.
Thank you for sharing. The bulb in the front of the cabinet is called the "pilot light" to alert you when the unit is on (powered up), but not necessary playing anything. This was a feature for tube type units and eventually went away in the early 70's as transistors replaced tube types.
Hello the Stereo is a classic gem of yesterday. I enjoyed watching the entire video. But i was disappointed that you didn't repair the turntable. I have watched other videos where the turntable was being repaired & restored. & very well worth fixing it. With the other side of the cabinet for records it's only half done. Wow how I miss my old DELMONICO console The Dino it was nicknamed that old brown turntable was junk However i replaced it with a newer model years later. Meanwhile it was educational experience to view. ✅
I'm under the impression these are really just worthwhile for the cabinets. That is, the electronics are just not worth the work to fix (for those that are not educated and with the proper tools that you have). I just picked up an old RCA a little bigger than that one and there is a terrible hum that makes the radio unusable though the turntable sounds pretty good. But the turntable has to be hand spun for about 30 seconds before it will lock on to a useable speed. The power supply has a couple of extremely large electrolytic caps that probably need to go (hence the hum), but when I can just throw in some modern electronics and a nice turntable, completely refinish the cabinet and put in good speaker components, It can become something truly hi-fi by today's standards, but still give the original look. That said, I'd love to have one that sounded just like new. They were never that good by today's standards (usually thumpy bass heavy, I actually remember that sound), but then, an MG TC doesn't handle like a modern sports car. It would still be a lot of fun to drive. :) But I don't have the equipment or knowledge (not to mention time) to refurbish the guts. So I go for the cabinet. :)
My grandmother had one of these units and for 35 years she had a a couple of vases and 2 pictures of her father in the Lebanese army, but never as children did we know it was a record player. So after she passed away 10 years ago I went with my mother to clear out all the furniture and only then did I know it was a beautiful record player. So I took it home and now play my record on it. It powered up and worked perfect. All I’ve done is to have the pots cleaned with deoxit.
@@RobsFixitShop I have this old suitcase unit and when I turn it on it has this s reach from the speakers and when I turn the volume for either left or right I get intermittent noise from them. Now I tested the pots with a multimeter and got a reading of 0.390 for a A500k, when I touched the left with middle and right with middle. I used the 2000k ohm setting. And also did the same with my cartridge and get no reading at all on all of them. What do you think.
@@RobsFixitShop is it ok to use B500k as replacement because I can’t seem to find any A500 in the size I need. I need a volume pot and a switch power / right speaker volume pot too.
Magnavox is awesome we had a 1972e high astrosonic speakers were encased in styrofoam back then strong bass from 8” woofers and horn tweeters for the high end down to the floor style.
DIY Magnavox wrench- some of you may be familiar with Magnavox's practice of mounting the faceplate with upside down PAL nuts. They provided their dealers with the proprietary "handi-tool" to allow easy disassembly. In my console one nut came out easily with pliers, but the other absolutely refused to budge. After several failed attempts, I came up with a sure fire DIY tool. Get your hands on a 1/4-20 x 1 3/4" coupling nut (such as Grainger #41JZ35). Make certain that it measures 7/16 (.438) across the hex flats, some providers have other sizes here. Drill our the threads to 3/8 inch. I don't have a machine shop, so I had to do it a little at a time with successively larger drills from 1/4". When you are done you will have your own Magnavox wrench.
I have another Astro-Sonic that had the PAL nuts and they really threw me for a loop. Like you, I ended up fabricating a tool but it was pretty rough. Go to 6:50 to see what I did. My suspicion is that you found a much better way:-) ruclips.net/video/A4Pyvu0NtNk/видео.html
A lesson learned by me on a 1969 Magnavox console with a similar amp. Replace ALL !!! of the electrolytic coupling capacitors. If not, you will chase cap failures throughout the amp
Interesting to see the insides of one of these old radio/phono consoles. I remember when they were the cat's meow. They really sounded pretty good. But now you can't give them away. They take up a lot of valuable floor space.
Too bad because I think its cool how you can blend in with other furniture and you can have a tv above it on the wall with the console hooked up for sound which is better than a sound bar.
You're just going to have to use your knowledgement for my question. I got a zenith record player with am/FM Everything works fine for the most part. now the sound! Lol the sound works on both sides,one side is normal the other side is next to nothing like only the highs are working and I tested the speaker with another speaker so it's not bad speaker.
You might want to check if you have audio coming out of the back of the chassis. If so you might want to check out the crossover. If it in the chassis you can try cleaning the pots and checking for cold solder joints and then moving on to checking the audio path for bad caps. Good luck!
This version has four germanium output transistors (2 per channel). These most likely are similar to 2N2147 or 2N2148's. Typical RMS power output of this configuration is 15-20 watts rms/ch.
Hi Rob! A couple months ago I acquired nearly the exact same model cabinet; works fantastic! Receives AM/FM clearly, plays records like a champ, speakers sound great! I just want to do restoration work on the cabinet itself - fix a dent in the frame, replace a torn speaker cover, apply new stain & varnish. Some of this work would of course require removing electronic components and then reinstalling them when the cabinet restore is complete. The problem is, I know zero about radio electronics and do not have confidence I could put everything back where it goes! I've tried finding resources to learn about these old radios so I can go in to the project armed with as much knowledge as possible, but everything I can find online seems to assume the reader already has a good understanding of radio construction & repair. How would you recommend a complete novice learn enough of the basics to do an otherwise simple restoration project without completely destroying the working electronics?
I wouldn't sweat it, the console probably has a wiring diagram inside on the floor of the console. Take a bunch of pictures of the current wiring locations. I was able to disconnect everything without desoldering anything. If you are worried about getting things back in the right place, label them with masking tape. Good Luck!
@@RobsFixitShop I'm in a similar situation to @paperip. I have this Maggie and got her a few years ago. I'm wanting to restore, clean, and do some upgrades like bluetooth. I would love some guides to those things, but it seems those things don't exist. Thanks for your video.
I have a Magnavox 1P3426 and would like to get it going again. Having a bit of a tough time finding someone in the Long Island area willing to try to repair it. Suggestions welcome! Thanks.
Hey Hey! Thanks for your video, very fun to watch. I recently picked up a vintage Magnavox entertainment center, but the Turntable was not included... The new turntable is connected to phono, but it fades out whenever it's turned on, and the power and amp go out. In other forums, they said it was due to the phono connection expecting the turntable and thinking there are no records to play and shuts off the system- they also suggest soldering a jumper between the "hot" and return wires of the turntable power harness. I'd love to know your thoughts on that and if you can do a demo of the soldering needed to make it work. I do not have the old Turntable and wondering if its the right solution because one end of the harness won't be connected to anything...
It's been awhile since I worked on it, but when phono is selected it expects the turntable to turn the amp on and off. You can make a jumper wire from automotive connectors and jump the bottom 2 wires on connector shown here: 1drv.ms/i/s!AgRy1tCE6lTdgv9ASoAqC5xi_o_pKA?e=WuufOj
For me, the record player is the most important part. I owned 3 of these in the 60 s to 70's I'm considering trying to find a nice one now, but if the changer doesn't work, I'm probably wasting my time.
@@RobsFixitShop I jus got mine back from the shop yesterday and it needs to go back. The changer is jamming in cycle at times and playing a bit slow at times. Also a lot of noise from the tone arm that is audible above quiet passages of music. Surprisingly, left channel output is still very weak, right channel blasts. He said I didn't tell him. He is 86 and has been doing this stuff since 1957, so I didn't argue. He said no problem, bring it back. It's a 5 foot monster to haul in my SUV.
Great, but the Astro-Sonic amps lost a lot of percussion response that the tube-types had. What tool is needed to get the Astro-Sonic unified chassis out of the cabinet? I heard something about PAL screws.
Can you share what schematics you used? I'm looking to repair one that's very similar (and transistor as well). Yours is the closest I've found so far and would appreciate any info you have on the schematics.
I just bought this almost same unit… AM works fine but can’t get FM to work at all. Anyway we can hook up and maybe you can help me understand the issue? All the tubes are working. All lights work… player works. Would appreciate any feedback or maybe we could connect through Facebook. 👍🏼🤷🏽♂️🙏🏼
Rob, I have a Magnavox 1P3605 Phonograph and Stereo. The radio will turn on but when I turn the tuner nothing will come on, not even static. The light comes on. The phonograph works beautiful. Any suggestions. No one around Eugene, OR fixes older units like mine. The insides look pretty much the same as the one you fixed.
Hi! I have a nearly identical Magnavox console, just a bit smaller. Its in great condition, but I have a problem I can't figure out. Loud and clear as day when playing AM/FM, yet muffled and only plays out of one side of speakers at very low volume when playing records. Any idea what might cause that? Thanks!
This one had a broken wire going to the phono head. I had to put in a new set of wires. The phono had a set of RCA Jack's on the underside. You could try putting some line level audio into the cable just to see if it is the phono or the amp.
did you ever think of changing the turntable for one with the same features three speed and automatic maybe he wants to have a turntable just the type that is curious some like records and many people like the vintage usage i think it was a great video i just ask questions to find things out and i myself happen to like things as is but a little updating to add to everything that it has is a nice touch all the best be safe and happy holiday season
That turntable is easy to rebuild, yes you will most likely need a new idler wheel, stylus, and maybe a power switch, but the rest is cleaning up old grease and relubing. I’m in the middle of my first VM 1297 right now and with any mechanical inclination, it’s pretty simple. Make you a deal, I’ll ship you my radio to fix, you ship me your turntable to fix! Lol
Hello, I have a Magnavox that is just about the same as yours. It worked great until about a year ago. We loved listening to our records on it. But now for some reason the record player no longer spins fast. I thought it would be a belt. Opened up the back and there was no belt. It looks like the gears are just running incredibly slow. Any suggestions on how to get the gears going smoothly again? I would LOVE to be able to listen to the records at the correct speed again! Great video by the way!
Most likely the grease in the mechanism has dried out; it's a common problem with older record players. The solution is to pull the changer out, clean out all the old grease, and re-lube everything. Do NOT use WD40 or 'red can' 3-in-1 oil. Those are penetrating oils and dry out pretty quick, you want something along the lines of light machine oil (sewing machine oil works well, or blue can 3-in-1; I like to mix a little spray-can lithium grease in as well). While you're in there, get a replacement idler wheel (the big rubber wheel he discusses in the video). There are services who rebuild them. Changers are complex mechanisms (MicroMatics especially so!); so if you have to actually disassemble something, take photos and be careful, there are some very small parts. Don't forget to lube the motor. You do NOT want to try to find a replacement for one of those.
Howdy Rob! I have a 60s magnavox hifi cabinet that’s been in the family since new. It’s in need of restoring or good for parts. Not interested in making money, just can’t stand the idea of it going into landfill. If you have any thoughts on where I might find an interested party I’d love to hear. Thanks!
Magnavox micromatic Many ebayers collect These heavy weight Mechanisms so Are in some demand To be repaired/ restored. Ebay prices for these can be up to $200.00 or more just for the Changer,
Hi Rob I have a similar magnavox that I am trying to get working. Right now only one drum speaker pushes any sound. I have tested the speakers and they are in working order. I’ve pulled out the main board and can’t see anything wrong but I don’t have the diagnostic equipment like you have. Any ideas on how or where I could get my board tested. I’m in Ga.
I am working on a similar stereo, and I can’t find the Sam’s publication for it. Which Sam’s number did you use for reference on this stereo? I believe it will be close enough for the one I am trying to repair. Thank you for the video.
I was hoping to see something that would help me figure out why my turntable won't spin. I inherited one of these pieces of furniture, the radio works, the record player arm moves. But the turntable does not spin.
I own the 1967 Magnavox Astro Sonic 4ST686 Collaro Record Player/ Radio Console Stereo Hi-Fi Turntable-Aux Input. HOWEVER, I can not find the input for auxiliary anywhere. Maybe you can help?
A red wire broke on my astro sonic 204 but i'm not having any luck tracing where it broke off .all i know is it comes up from under the stereo fm board
THE RECORD CHANGER WAS MADE IN ENGLAND OF HEAVYWEIGHT MATERIALS, IT IS NOT A CHEAP THROW AWAY ITEM. TO SOME. PEOPLE BUY THESE CHANGERS ON EBAY ALL THE TIME. EVEN WHEN THEY DO NOT WORK PROPERLY FOR PARTS., RESTORATION.
@@lordalexjones1177 Yes, the wire between the cartridge and the RCA jacks was broken and beyond repair. I tried using a wire from some ear buds but it was too stiff. I ordered a wire made for the job from ebay and soldered it in. It was kind of delicate work but the owner (a friend of mine) was thrilled. It still needs the idler when replaced but I showed him how to do that. It sounded pretty good.!
a wire from the preamp on my 204 chassis broke off at the other end but i'm having a very hard time , finding what it goes to the schematic is too hard to understand
i just picked up this EXACT model at a local garage sale for $25, came with several boxes of records. I apologize because I'm still watching the video but I wanted to ask about the tuner mechanism. This one is frozen and stuck on one frequency and even if you take off the knob it cant be moved with pliers. Whats the best way to loosen this? are there replacement parts available for it?
I’m noticing the Gophers t-shirt and wondering if you are in Minnesota? And if so, do you do repairs for others? I have my grandparents console from the 60s (estimated). The radio works but I think one of the speakers might be blown. The turntable turns but no sound. I would love to have it refurbished. Is that something you do or any recommendations in the mn area?
Dude, this is exactly what my Grandpa used to do with EVERYTHING. It's not an age joke. Thank you for this.

I remember the days of knobs and dials. They were killed by remote control.
Can you share what schematics you used? I'm looking to repair one that's very similar (and transistor as well). Yours is the closest I've found so far and would appreciate any info you have on the schematics.
I just bought this almost same unit… AM works fine but can’t get FM to work at all. Anyway we can hook up and maybe you can help me understand the issue? All the tubes are working. All lights work… player works. Would appreciate any feedback or maybe we could connect through Facebook. 👍🏼🤷🏽♂️🙏🏼
I couldn't believe how out of alignment that thing was.... was someone in there before you?
I have what I am guessing a late 70s or 80s consul cassette/radio/record player. Any idea where to get repair manuals? Parts lists?
Rob, I have a Magnavox 1P3605 Phonograph and Stereo. The radio will turn on but when I turn the tuner nothing will come on, not even static. The light comes on. The phonograph works beautiful. Any suggestions. No one around Eugene, OR fixes older units like mine. The insides look pretty much the same as the one you fixed.
I would definitely clean the tone controls and switches. The signal path goes right through them and if they are not conducting, nothing.
Do you do troubleshooting for people who have problems with their vintage stereos?
Nice job.
I would have fixed the turntable.
I like the Bluetooth idea,
But I would change the internal speakers as well as using external speakers.
i found a place in Jacksonville fl called bulbtown and got the 2 volt bulbs foe the stereo fm indicator
How has the restoration been going?
@@RobsFixitShop haven't done anything in awhile
I have an identical one except for the styling. Want to do another one?
Hi! I have a nearly identical Magnavox console, just a bit smaller. Its in great condition, but I have a problem I can't figure out. Loud and clear as day when playing AM/FM, yet muffled and only plays out of one side of speakers at very low volume when playing records. Any idea what might cause that?
Thanks!
This one had a broken wire going to the phono head. I had to put in a new set of wires. The phono had a set of RCA Jack's on the underside. You could try putting some line level audio into the cable just to see if it is the phono or the amp.
did you ever think of changing the turntable for one with the same features three speed and automatic maybe he wants to have a turntable just the type that is curious some like records and many people like the vintage usage i think it was a great video i just ask questions to find things out and i myself happen to like things as is but a little updating to add to everything that it has is a nice touch all the best be safe and happy holiday season
Do have a video on how to make the dial strings work? Mine came un done and I can’t figure out how to re-string it.
That turntable is easy to rebuild, yes you will most likely need a new idler wheel, stylus, and maybe a power switch, but the rest is cleaning up old grease and relubing. I’m in the middle of my first VM 1297 right now and with any mechanical inclination, it’s pretty simple. Make you a deal, I’ll ship you my radio to fix, you ship me your turntable to fix! Lol
I have a one of these turn tables that I have been having a hard time getting to work. Would you be interested in helping me?
Hello, I have a Magnavox that is just about the same as yours. It worked great until about a year ago. We loved listening to our records on it.
But now for some reason the record player no longer spins fast. I thought it would be a belt. Opened up the back and there was no belt. It looks like the gears are just running incredibly slow. Any suggestions on how to get the gears going smoothly again? I would LOVE to be able to listen to the records at the correct speed again!
Great video by the way!
I wish I could help. I have yet to get a a record player working right. For a guy like me that loves to get stuff working it is really frustrating.
Most likely the grease in the mechanism has dried out; it's a common problem with older record players. The solution is to pull the changer out, clean out all the old grease, and re-lube everything. Do NOT use WD40 or 'red can' 3-in-1 oil. Those are penetrating oils and dry out pretty quick, you want something along the lines of light machine oil (sewing machine oil works well, or blue can 3-in-1; I like to mix a little spray-can lithium grease in as well).
While you're in there, get a replacement idler wheel (the big rubber wheel he discusses in the video). There are services who rebuild them.
Changers are complex mechanisms (MicroMatics especially so!); so if you have to actually disassemble something, take photos and be careful, there are some very small parts.
Don't forget to lube the motor. You do NOT want to try to find a replacement for one of those.
who is your tester made by i need one that will test capacitors but can't spend much
Howdy Rob! I have a 60s magnavox hifi cabinet that’s been in the family since new. It’s in need of restoring or good for parts. Not interested in making money, just can’t stand the idea of it going into landfill. If you have any thoughts on where I might find an interested party I’d love to hear. Thanks!
you used fishing line as tuning dial cord? i'll have to remember that
I just got one of these but a different style radio works but the record player doesn’t spin is there a way to fix that
That's all fastina I be go set up an you got there.
was looking for help with the turntable you just added some blue tooth something in
did you build the thing you tested the capacitors with?
Ski u mah my friend!
i've got one like that and one channel is noisy could some capacitors be the cause?
i got my first 2-volt bulbs from bulbtown in jacksonville fla
Magnavox micromatic
Many ebayers collect
These heavy weight
Mechanisms so
Are in some demand
To be repaired/ restored.
Ebay prices for these can be up to $200.00 or more just for the
Changer,
I just got a garrard synchro lab 55 b it’s making a noise but can’t get it to work
Hi Rob I have a similar magnavox that I am trying to get working. Right now only one drum speaker pushes any sound. I have tested the speakers and they are in working order. I’ve pulled out the main board and can’t see anything wrong but I don’t have the diagnostic equipment like you have. Any ideas on how or where I could get my board tested. I’m in Ga.
I am not sure where you could take it but I would clean the controls with some electronic contact cleaner before anything else.
Where did you find the schematic? I'm having trouble finding it
My mom still has her console like this. I think only the turntable works.
Are you located in MN? I have a Magnavox Micromatic from the early 60s as well. One speaker & sub cuts in and out. Would love to have it serviced.
I am working on a similar stereo, and I can’t find the Sam’s publication for it. Which Sam’s number did you use for reference on this stereo? I believe it will be close enough for the one I am trying to repair. Thank you for the video.
I was hoping to see something that would help me figure out why my turntable won't spin. I inherited one of these pieces of furniture, the radio works, the record player arm moves. But the turntable does not spin.
Broken teeth on gears possibly
what did you clean the dial glass with? you did a great job
What size are the bulbs that light up dials and meter
i think i figured out where the wire broke off, luckily i already have decent wire to replace it
I wish I could find a person in my area to fix one. Everyone that looks at it says they won't even touch something that old.
Hello would you like to tune mine, I have the same one. It is in working condition at the moment
Why was the record player not worth fixing? Just preference or was the wheel you needed to fix not going to be the key to fix it all
I think it is worth fixing, I have just had bad luck working on them. It's one of those rare times I pay attention to my lack of experience :-)
i just bought a micromatic changer that has ref.no of 6446
Is there a reason you wouldn’t replace it with a 3 prong cord? I apologize if I missed it.
It goes right into a transformer so it is isolated, although it would be even safer with a 3 wire
I just found this same record player but I can't get records to play, it will start to spin and then stop please help!
I own the 1967 Magnavox Astro Sonic 4ST686 Collaro Record Player/ Radio Console Stereo Hi-Fi Turntable-Aux Input. HOWEVER, I can not find the input for auxiliary anywhere. Maybe you can help?
If you were in Iowa I'd have some work for you sir
Magnavox is from Phillips....
45:50 - That's why they make Rubber Renee!
i'm working a changer just like that now if you need help . i 'll be happy to answer any question i can
Are you located near Baltimore md. I need someone's to fix my magnavox stereo console
A red wire broke on my astro sonic 204 but i'm not having any luck tracing where it broke off .all i know is it comes up from under the stereo fm board
is that a 204 chassis?
I found one at goodwill for 40bucks it's like new but has a humming sound
New capacitors in the power section should help
Hello! I recently acquired this exact same model magnavox -would you recommend putting new thermal grease on the output transistors?
I didn't, it is kind of a low wattage model and it didn't seem to be putting out a lot of heat but if it looks crusty then the less heat the better.
It wouldn't hurt, but what smokes components are defective power supply electrolytic capacitors.

I am going to take another look at it, the owner wants to fix it. Thanks for the input.
@@RobsFixitShop did you have any luck?
@@lordalexjones1177 Yes, the wire between the cartridge and the RCA jacks was broken and beyond repair. I tried using a wire from some ear buds but it was too stiff. I ordered a wire made for the job from ebay and soldered it in. It was kind of delicate work but the owner (a friend of mine) was thrilled. It still needs the idler when replaced but I showed him how to do that. It sounded pretty good.!
@@RobsFixitShop Where do you get your parts?
@@lordalexjones1177 I have had great luck with DigiKey for most stuff
Can you help diagnose mine?
i think NTE bought the Manufacturing rights to Sylvania's part catalog
that resistor is the 2.2meg. what does the 2.2meg resistor do?
Are the capacitors you put in intended to replace the filter capacitor in the power supply
when you outside of the rectifier do you mean the negative side?
a wire from the preamp on my 204 chassis broke off at the other end but i'm having a very hard time , finding what it goes to the schematic is too hard to understand
my astro sonic quit on me this morning and doesn't seem to power up. can you give me an idea of what to look at?
I had to get a new socket for my stereo fm indicator. the wire broke out of the center in the bottom so i ended up getting a bunch
is that a desoldering tool ?
i just picked up this EXACT model at a local garage sale for $25, came with several boxes of records. I apologize because I'm still watching the video but I wanted to ask about the tuner mechanism. This one is frozen and stuck on one frequency and even if you take off the knob it cant be moved with pliers. Whats the best way to loosen this? are there replacement parts available for it?
I would pull out the chassis and oil the shaft and just gently work it.
the last word is fidelity on the panel
Hi. Where can I purchase a new mirror for my 63 Motorola. Or other record players that i own ?
I meant needles
I’m noticing the Gophers t-shirt and wondering if you are in Minnesota? And if so, do you do repairs for others? I have my grandparents console from the 60s (estimated). The radio works but I think one of the speakers might be blown. The turntable turns but no sound. I would love to have it refurbished. Is that something you do or any recommendations in the mn area?
I'd like to know, too. Have a similar Astrosonic here in Minneapolis that could use some going through.
