The worst cassette recorders ever are new chinese shits such as boomboxes, which record one big noise and very dirty sound, don't have a mic or input jack, damages few days or months after buying, and CD makes some noise like a tape.
I'm an amateur solo musician who has never done a gig and I love cassette players. I bought this "Realistic" tape player from the local thrift store $2.50 and boy was it crap it kept making ticking noises, and when I recorded my music the damn ticking noises would get caught in the recordings and they would sound flat.
Now I own a Panasonic Am/Fm and tape recorder with a 5 band equalizer and has a built in condensor microphone. The only noises that get's into my recordings are occasional rattles. The model is RX-CS700.
That sounds pretty bad, but I should send you my General Electric 2002 portable cassette recorder. That sounds absolutely awful. It can play my cassettes well, though even though its mono.
I have a Magnavox cassette recorder with a similar speed problem. It is the motor. In the Magnavox, the brush springs are too weak to keep contact (who knows why they did that) so they augmented them with rubber springs (no kidding). Of course, over time, the rubber dries out and afils, so the motor is dependent on the springs that are too weak, hence the speed comes and goes.
I'll assume that the simple stuff (cleaning, demagnetizing, FeO2 tape) has been checked. Had a Lafayette deck with this; I assumed the head wore to the point at which is wasn't concentrating the flux properly, never found out for sure. Most cheaper recorders had DC bias, so you should be able to check it by measuring the current though the record and erase heads. I assume they both need some DC, but I'm no expert on biasing; you'll need documentation on that model to know what it should be.
The regulators I've seen seemed to be electrical; they probably were designed to "guess" the speed from frequency of the motor noise, or something like that. Anyway, the speed adjusting trimmer potentiometer on these would eventually get noisy, causing the type of slowdown in the video. Some tuner cleaning spray might fix it, after which the speed will need to be re-calibrated.
Try spraying the record-play switch with WD-40, and for the speed, the motor probably needs oil. For the sound quality, DC bias? I'm not exactly sure, the bias might be set too low. Usually near the bias coil there is a trimmer resistor that controls the bias, and if there is one it might be either dirty or set way too low, and not biasing it enough. I had fiddled with the bias control on a good AC bias machine, and doing it too low resulted in a similar recording I believe.
It seems like this unit contains bad capacitors, but you should also control the internal record/play switch. If those switches are oxydized or dirty, the recordings also sound bad. Maybe the switch in your recorder is so bad that it es not able to switch on the bias. Did you used a normal position cassette?
Reminds me of my 1st one from Radio Shack!!

sound begins at 1:37 thunbs up to show this every one who clicked only on the video to hear the bad sound quality

What exactly is bias for!
My old Sears stereo sounds like that in recording.

I have an old Sanyo that records like that, it sounds dreadful, I can barely understand you.

you should ask CassetteMaster whats wrong with this recorder he is good at fixing these machines.

Definitely no bias there. I've heard how a recording sounds when the bias isn't being added, and that's what it sounds like to me.

As for the wobbly sound,l wonder if this has one of the older type motors with an electro-mechanical speed regulator.They
were widely used on cheapo models,and
tend to act up.They're VERY fiddly to get right.Maybe the record-playback switch is
dirty too,hence crackly sound in places!

It sounds like that because.....well....it's an Emerson. They were always cheap, even back when they made tube radios in the thirties and forties....

My mom bought a stereo from them when she was a kid, and the 8-track player never worked.

I do have to push rather hard on the record button to get it to lock down, so maybe the internal switch is part of the problem.

Holy crap that is bad, probably some bad capacitors I wouls guess
coolbluelights 3 years ago
I would go looking for bad capacitors...using an ESR meter would be good. It is old enough now that caps may likely start to go bad.
retrochad 3 years ago
It also has a lot of AC hum, especially when starting or stopping the motor. So yes, it likely has bad caps.
