- 3OTD brings a 1961 Symphonic turntable back from the dead! We test and troubleshoot our way through the unit, which had no audio output although the turntable itself was functioning. A good old-fashinoned "suitcase" record player!

Thanks for making this video because there’s literally no other video like yours.. lol it’s like why don’t more people still love these wondrous old machines !!! ❤
I'm astonished that the cartridge could still function. Those old Rochelle salt crystal things had a bad habit of soaking up humidity and deteriorating to power..
Everything was made solid and made with parts that you can change and replace, and a touch of art to it. Now everything is made from plastic and the electrical aspect of it is computerised and can’t be fixed.
My mom had one like it.
This is Marcia again with the symphonic 1960s stereo It says model 1625 and my little doodad at the end where you switch it to a 78 is different looking than yours
are the output tubes 50EH5's? if so that's a very good amplifier, Magnavox made amplifiers like that
This is the kind of repair that a novice should not attempt. Watch some videos on cartridge replacement at least. You will find out that the 4 soldered pins
should not be soldered to the cartridge. Instead get a set of solder lug connectors. They fit inside the four brass colored tips of the cartridge!
Nice to see you found that the three speaker system can be converted to just using the main speaker! The turntable grease shows she may need
some cleaning out and relubed using a proper grease like white Lithium grease. The owner can do that as it will turn much better.
I didn’t solder it to the pins directly, I cleaned up and re-used two of the lugs that slip onto the pins if I recall. -Tim
Do they make replacement styluses for these old cartridges?
I have a similar symphonic model 1700 suitcase record player that sounds a bit scratchy, and I think it’s the needle causing the issue. My cartridge looks quite similar, though mine’s a mono turntable with a single speaker and a single tube. Mine has a simple motor mechanism that runs straight from the 120 volt supply and has a mechanical switch that moves the idler wheel up and down on a shaft to play the different record speeds. Also could be a speaker issue, but that needle is making so much noise on it’s own, Also, is it normal to take a minute or so for it to start making sound? I’m not familiar with tube amps.
I suggest you measure your wires to see if there are high voltages or any voltages before you begin touching them and a possible HOT chassis that could greatly injure you and or severely damage hard to find amplifiier components
Great job, I think you should next grease it all up, change the caps.
Yeah, wish I could have done a further dive into this unit, but it went back to it's owner not long after the clips were filmed for this video. - Tim
I have a symphonic probably 1961 stereo but do not know how to replace the needle. can you help me. My son-in-law bought me a tiny little needle but I don't know how to put it in this old cartridge? Thank you Marsha
Great tutorial! I have an RCA suitcase turntable, guessing 1950s. It's in great shape and works great but volume is low. I am not sure if I need a new stylus or if something else is going on. Volume dial does work just not a lot of volume. ANY IDEAS? Thanks!
Corrosion on volume control surface.
I just bought an old Monarch three speed multi changer radiogram and surprisingly need to do little to it. I need to resolder the speaker connection pins on the needle and figure out why the 45 and 78 speeds work but the 33rpm fails. Hopefully watching these vids will help :D
Sounds neat! Good luck on fixing it up!
@@3oldtechdudes just have to remember it's 70 odd years old plastic, so not to be too rough. Pity the radio is analogue and doesn't have anything to pick up anymore.
i had a magnavox 3 speed changer and the idler tension spring turned out to be fatigued so i replaced that and oiled the motor again and the 33 became normal
@@larryshaver3568 In my case the mechanism that controlled the speeds just needed to be cleaned up and reset/tightened in the right part. Nice and easy job.
Maybe I didn’t let the tubes warm up long enough?
Hi,I’m restoring a Regentone record player with a Collaro turntable,approximately 1960s ,The 3 potentiometer switches are knackered,I’ve tried the cleaning procedure with contact spray but no improvement, The pots have a plastic shaft,with a flattened side,But I cannot see any reference number values on the pots, 1 is on pot,2 is volume pot 3rd is tone pot,can you let me know the values needed please,any advice would be appreciated.
I have one of these that I got off my local buy nothing group. Unlike this one, I have all the speakers. But the turntable does not turn. I hear that electricity is running if I turn it on, but the table doesn't spin. I have taken it apart to watch what should happen if the table spun, but do not understand the root issue. Any suggestions?
It is a stereo cartridge. You have right and left signal and right and left common.
I have a Decca RG98 Radiogram fitted with a R.C.111 Garrard turntable and I'm having similar problems. I get no audio whatsoever when I brush the stylus but I know that the speaker works as the radio is audible when turned on :(
I have a 1961 symphonic 1731 that acts weird sometimes, while it works for the most part, sometimes current will run through the secondary arm that has something to do with its 45 stack system. gives quite a shock if not careful, and the speaker volumes arnt equal, with the left one being much more quiet than the right
I wonder if that model has a "hot chassis". Since these units are too old to have a polarized plug, it may be that the "hot" side of the outlet is plugged into the neutral side of the turntable's motor wiring. If it does this in the future, try unplugging the cord and rotating the plug. If the secondary arm isn't energized, that's the answer. (Might be good to use an A/C detector near the secondary arm to check this, of course! Less painful that way!) - Tim
Lead to the needle is disconnected somewhere and touching the arm.. probably the red wire close to the needle ... the yellow one is the right channel. Remove the prong ,resolder and reattach.. should be good 👍
Use shrink sleeping to cover your solder joints not tape if available.
I just got an old tube record player and I don’t know what’s wrong the wires seem good but no sound, I can hear the recording but very quiet
If it's as old as this it's possible (likely, even!) that the crystal in the cartridge has deteriorated. I was actually surprised the one in the video still had life in it.
Those old crystal carts tend to soak up moisture over time and go to a crumbly powder. Modern ceramics don't have that problem, but generate a much weaker signal.
Great video. I have an Arvin P 38 with what looks like the identical Ronette cart and the pop on needles. Its 3d sterophonic sound system with VM 1223 table on it. @ 61' - 63' I have the photo facts for this and I have my tracking set to 5 grams ( calls for 5 - 7 g ). I'm having trouble with needle skipping or jumping on the newer records that there coming out with mainly during hi bass tracks. I have replace the needles twice and it still does it. I've been told that it sounds like a set up issue but again photofact only shows about weight and arm drop location. Any idea as to what I may be missing or overlooking that may not be mentioned in the photofact
That Arvin antique isn't capable of playing modern LP discs. Today's LP discs don't have their bass filtered to track on 60 years old phonos. They expect magnetic cartridges of higher compliance tracking at 3 grams or less. And on precision tonearms. Sorry, reality.
Anyone maybe know why one a 1978 Sony hme 338 why I can't move the switch from stop to start or auto it feels like it will break if I try to pull any harder than I have which I could add pic :/
Hi y'all. I was wondering if you had any advice for the following issue: I have just bought a vintage HMV 2417 record player but it has built in speakers and they're really crappy. Is there a way I can discconect them and play it through new speakers? Thanks!
You could likely get in it and disconnect the original speakers, add some speaker wire for each channel connected to the original lines, and run them out of the cabinet somehow to better speakers. That often will be sufficient, and was actually what had happened to this Symphonic in the video. The catch with the Symphonic was the 3 speaker design made that more challenging due to how it was designed.
Where to find new needles for it?
Capitol made a stereo record player like that with a bsr monarch instead of a Telefunken
the red and blue are the right channel and black and white are the left channel
A Symphonic record player
from the year 1961, correct?
Yes, that’s correct.
