- Unraveling some of the mysteries behind these modern type turntables. Emerson nostalgia 4 in one unit with a non-functioning record player. This model turntable has the auto-return feature, & is fitted with a ceramic pickup. Motor is suspect, & steps are taken to confirm the issue. Testing the motor supply voltage, & also, why is there a lack of amplification when switched to phono. Also piecing together just how the 3-speeds are created via. a 2-speed motor. Motor spindle, pulley, platter sizes, types, etc., all play a role in determination of the 3-speeds. Motor was defective on one unit. A second unit was used to determine the value of the motors shunting resistor, (22 ohms), after suffering discoloring from running with the shorted/defective motor. Suspect an OOB-type failure, or not long after. Turntable showed little, if any use. Both units now function proper.
Thanks for posting this! I have this exact model and while I’ll concede it’s not exactly top quality it was a gift and holds some sentiment. Recently my table stopped spinning and I’ve been working out figuring out why and seeing you disassemble a functioning one was really helpful.
please get a tripod to hold the camera - it would help your videos endlessly - giving you both hands free and able to give the viewers a solid video to watch - and make your showing how the repairs and parts are much easier
Interesting video but, quite frankly, I'd have a vintage VM any day.
Belt broke, searching for proper replacement. The Amazon: M-Tronics Replacement Turntable Belt for Emerson NR-303TT was too loose. What a pain. A simple rubber band might be enough for this cheap find. Still have to locate an appropriate size.
Have one of these now. surprisingly nice speakers to be honest. Being a youngin didn't use the record part til yard sale time. Motor died after maybe 4 of the new vynils bought. Probably shoulda got the old school player from the old couple while I was at it as they were apparently happy enough with the new echo dots or w/e. Sigh
Recently purchased one of these (very cheap) and the tone arm refuses to lower at the beginning of the record. Any tips on how I might fix this? Thanks
Emerson Radio Corporation is actually still a real company believe it or not. Although they are owned by Funai, they still operate independently and are among the few consumer electronics companies that have survived over the years. Here is their website: www.emersonradio.com/ and stock: www.thestreet.com/quote/MSN.html
I give you credit for even trying to fix this thing at all. These are HORRIBLE. The CD player works decently on mine (even though it makes horrible noises), but the turntable is not worthy of playing any record.
There is a way to adjust the shutoff on these. I THINK I see the adjustment about halfway up the right-hand side of the video at 26:11. It's been a while since I messed with one of these. I used to have one with the very same cabinet design. One odd quirk was you could make the motor run by holding the selector switch between phono and whatever was below it.
Hello, & thank you for watching. Yes, there's typically a set screw to adjust the trip, & the designs vary. None seem to work flawlessly, & they have been trying different methods. Mechanical, & electrical, or a combination of both in an effort probably to help inhibit skipping before tripping, or stopping dead, just shy of the leadout groove. Seems hit of miss, even with adjustment.
@@Farmradio Around 3 months ago, I got the ultimate replacement. A Crosley C200 Direct Drive Turntable. I've been gradually building a component system centered around a Sansui 551 amp. I have an 8 position component switch that's almost filled up. Bluetooth, WIFI, DVD player serving a CD player. The DVD player is also connected to a late 80's knob tuned Zenith Custom Series TV that I got for free. Somebody nearly ran that set into the ground, but it plays good enough.
@@Farmradio hey can you send me the diagram for this motor? With the pinout and speef configuration.

Hello! You've posted some very useful information, but I have a request. Could you possibly post a better look at your notes? I'm trying to decipher one of these things for a custom project.
What was the motor part number again?
At 31:03 there are two solder points touching each other, couldn't that have caused your motors issue?
Hello they are either touching each other from the factory, or appears as such. In the end, it was a defective motor. Thank you for watching!
Got one. But has no power
My grandma had one of these all in ones and I replaced it with a very cheap early 80s Montgomery Ward stereo with BSR truntable the Montgomery Ward has way better sound quality then the all in one that was made by RCA and RCA player is now RIP.
The quality floor has gone WAY down. What was cheap junk in the 80s is like top quality in comparison to Chineseum junk. Nothing was made this bad back then.
Unfortunately, I used to have one of those............ mine never worked right.
Unfortunately, these types of record player units are being unleashed on the unsuspecting general public, by the boatloads, (or container loads these days), but there's always been the case of getting what you pay for. Am no way implying nor advocate that these are good quality players. Try not to play prized copies of anything ie. tapes, records, on these. CD would be the only exception. They cant harm a CD. Reserve these for playing some 78's, scratched, worn copies of records, etc. For what they are they do the job. They can be problematic motor-wise, & needed to get to the bottom of their design. When one finally upgrades to a high grade quality player, with a lightweight/high quality pickup, they may notice the degradation of their records caused by these, which was not apparent when playing thru these types of players. It's due to the higher quality units picking up all the wear these may have caused prior.
These units came with a bad stylus it is recommended. to replace it with a better one as the stock one damages the records
Yes, agreed. That is addressed in a future video on a similar player. IMO, Seems to be no issue with "most" factory supplied styluses, however website knock off-look alikes have caused banding of the grooves, so visual, you can actually see it while playing under the right light. Not good. Anytime a playing stylus causes the groove to change appearance that means trouble. Brand name replacements (ie Pfanstiel), do not exhibit any banding. There are a lot of very poor quality replacement needles out there. Bought 10+ no name replacements on-line, eB, etc. & all are of terrible quality under magnification, just terrible.
Does anyone know what year these are?
This model was made in 2004
It's funny how nowadays cheap Chinese motor's bugger up your record players. I am pissed off with them , I was foolish enough to buy what I was under the impression was a descent record player. It should have been it cost over £200, the weakest link for the record player? the motor. I set the speed , all's good then next time I use it you've guessed it slow as hell! I would not care but I have a old B.S.R up the stairs in my bedroom 40 odd years old never lost its speed. I just wish I could get my new record player to do the same!
What junk! 1950-1970's 3 & 4 speed mono kiddie record players such as Imperial, Columbia, Symphonic etc. had more quality components than these things. In their time they were the junk selling for $12.95 or less with cardboard cases and motorboards.
"MADE IN CHINA SUFFIX B", what in the he!! does that mean?? As for "BSR Mcdonald" references, I played many 'a record on them, with only stylus changes, and some normal maintenance; I, too, think they got a bum rap.... Boy, did we ever head south during the 1980's....
The opposite of "PREFIX"? Learned that in school anyways.
I notice that all these cheap players utilize the same turntable/ tonearm as if one supplier is producing these for all cheap brands made in asia... everyone use to make fun of the very common / cheap changer BSR.....compared to these junk of today... BSR is the premier top of the line....the motors I have trouble finding, are the motors for cassette players... when you do get them , they are built so cheaply the wow and flutter is horrible
Growing up with BSR's, Glenburns, etc. years ago, yes they got a bad rap, then, & still do today. They were affordable for the masses. Decent quality. Many were abused. Can say, never had a bad motor in a BSR, or hard idler, & never seen any significant record damage caused by them, even with Polystyrene. Can still use most all of them them today with little restore effort. Their early rubber mats are another story. Potato chip/warped rubber mat at the sight of any heat. Yes, good motors are the golden egg, & hard to come by, & have a lot of proprietary designs, on purpose it seems.
These players are so bad....
mine has ruined records I haven’t played yet!
So much hassle trying to fix such a low $$ rig.
Emerson of the past was a dime store brand. Bottom of the barrel.
