Compared to MP3 the sound may seem OK. When compared to an LP the tapes sounded noisy and lacked high range even with the latest version of Dolby noise reduction and "metal" tapes. I mainly made tapes for car use. My last deck was a Pioneer CT-6R.

It's sounds amazing for a budget cassete player and they look great.

Yes, and those were some interesting tapes he played.

I have a SCP-31. Original owner. And it still works! I worked for Radio Shack in the 1990s, and purchased one because of limited space in my apartment. It's not definitely not a Rolls-Royce among tape decks - more like a Volkswagen - but it definitely did the job it was designed to do. Music played on it was clear and an easy listen. It may not be the best, but for the price a SCP-31 can't be beat.

I have two of these, in working condition. Discarded by our church when we went to CD recording some 15 years ago. (We've since obsoleted the CD burner, too, outputting from the mixer board to a SSD.) I keep these two decks for the occasional dubbing request; some of my fellow geezers have family cassettes they have not heard in years. The Shack also made a tiny AM-FM stereo receiver, about the size of a clock radio. Got one of those, too, and it also works like a champ.

I picked up the Realistic version at an estate sale last year for a cheap price. Mines needed belt and a disc capacitor resoldered in the inside the metal shield. Working great ever since. It’s was made April 1990.

Love the Optimus stuff. I still use my Optimus system from 1991. I remember buying it and having to unbox some of it so it would all fit in my Chevy Cavalier. The speakers are huge.

You had me at "1991" and "Cavalier." I owned a '94 Cavvie 2-door once, that car was VERY good to me. Bought it from 2nd owner (1st owner was actually that stereotypical Little Old Lady) at 77k for $400, and I got t-boned by a Corolla at 236k, still on the original clutch when it went to the junkyard. (After the Corolla hit me, he got rear-ended by a Jetta... The only car not requiring a wrecker was my Cavalier!) Only left me stranded ONCE, when the fuel pump failed. I'd get another one in a heartbeat if I could find one. I told a friend of mine once that I was going to grab an office chair for free on the side of the road, and he said, "you won't get that to fit in this car." Five minutes later, he had to move the passenger seat up two clicks, and the office chair was upside-down in the backseat. (My butt is currently planted in that same office chair sixteen or seventeen years later!) And Brett - are you talking about the Optimus 10-band EQ with separate EQ for each channel, the "IMX Expander," and the tiny-dot LED spectrum analyzer? I had one of those too, I loved it. Unfortunately I fell on hard times and lost the contents of my storage unit years ago, that EQ was in storage at the time. 😢

I enjoyed this. It was interesting when you pointed out the lack of a power switch, I hadn't noticed that. That got me to thinking how receivers used to have power outlets on the rear. I had a Yamaha CR-620 for many years, I believe it had a switched and an unswitched outlet on the back. So, you could have plugged this into the switched outlet and it would have turned on and off with the receiver. Those seem to have disappeared over the years.

Believe it or not there's a switched outlet on the back of my AudioSource AMP 100. I don't use it, since the (rather large) toroidal transformer already whines and it's gotta be pushing some of that back into the mains power. I put that amp on the other side of an isolation transformer even though it doesn't make the whine any less audible. This is some off the shelf black box from Parts Express ten years ago, too. Hardly anything in it other than the transformer and the heatsink for the transistors.

When I worked at radio shack, these had a reputation of being very reliable despite the outward quality appearance. Had a customer who bought a number of them tell his success with them, but were the auto reverse higher up version that had Dolby? Been so long I could be wrong, but I remember us laughing about having Dolby for telephone on-hold, but only way to get auto-reverse in that model. Told me they actually were the longest lasting tape decks they could find for their on-hold music systems. Long chatter, but old memory that came back.

I remember seeing these used in my elementary school. They were added to the stereo in the music room, office and gym where there was previous only record players.

That was several seconds of fine music, glad we paused for it. Seriously, it does sound like a good unit! Excellent repair.

This came from a good period in Radio Shack history, before the default answer to any question about a product was "Would you like a cell phone with that?" And thanks for showing the insides in the video, I've got the SCP-25 from just a few years earlier and always wondered if Radio Shack changed the internal mechanism as they transitioned from silver to the "black plastic" look...

I bought the playback only and the record deck on Ebay to go with my matching Optimus am/fm mini Amp which they were designed to compliment. Due to the age, I was hesitant, but was so pleasantly surprised. They were used in a garage work space (as it was described). Upon inspection,they were barely used, almost brand new. Both in excellent working condition. Okay they don't sonically reproduce like my larger system, but, for the den/guest room, the system produces beyond satisfactory sound. They, and the mini Optimus amp, connected to my large 70s vintage floor standing 3way speakers please these discerning ears.

My biggest gripe with these was how light they were. It was hard to use the transport controls without the player scooting all around the shelf. Thats why it was duct-taped down. The alternative was to hold the thing down with one hand and push the buttons with the other (or you could do the spanned thumb-index finger thing). By the way, the companion SA-10, SA150, and SA155 'mini' amps that these were often 'bundled' with also had the always-on PSUs, with the power switches wired into the secondary side. I don't like that 'feature'. It's why I have all my electronics connected to power via a power strip.

Still, quality is better than most that is being released today. Wow and flutter especially.

And this is why I am happy my sherwood s-7100a has a switched outlet, the turntable is powered off when the receiver off! Glad you were able to save that deck from landfill.

"We will now pause for several seconds of fine music."

This brought me some much needed joy today. Glad to see forgotten things like this get some new life. My grandma had one like this many years ago.

It's cute as heck. I love the compact design it doesn't look super dated! Totally agree on the nakamichi! Unless you're archiving super rare cassette only releases then there's no reason for the average person to use a nakamichi and this would make a fine budget tape deck.

I had this exact model back in the 80s when I was a road musician. I loved it. Small and compact with a great sound.

I miss old catalogs like the ones you showed here. They were great bathroom reading material back in they day. Radio Shack, Crutchfield, etc. Seriously!

haha I love the cue cat bar code at 1:50 in the catalog. That sure didn't last long, but it was a good source of cheap bar code readers you could modify with a simple operation to turn it into a regular barcode scanner.

This thing is awesome! Nice repair. I appreciate you leaving your incorrect guess in too, you could have easily edited it out to make it seem like you got it right the first time but repairs are all about making mistakes and fixing them.

For anyone wondering why that happened, the 12V AC is RMS (Root Mean Squared). The smoothing capacitors will charge to the peak voltage which you get by multiplying by the square root of 2 i.e. 1.41. So once it is rectified and filtered 12V AC becomes almost 17v DC. The transformer manufacturer will also allow for the voltage dropping on load so the off load voltages were even higher,

I find it oddly amusing that the model name starts with *SCP* . Jokes aside, I love its petite size.

The website is designed to look like the user is logging onto a secret government agency's website with the format of each story being written like entries in a catalog of monsters and mysterious items or locations.

At least it's not a knock-off of the Tanashin mechanism, and does have a genuine Mabuchi motor. That's already more than what you will find in most "modern" cassette players - which will also cost much more. All in all, I'd say that was a nice thrift store finding.

I repaired those when they were almost new since my shop worked on radio shack gear across from their store !

Talk about nostalgic !!! Wow ! How I miss the good old days of analog!! Thank you.

Wow what a flashback. Worked at Radio Shack during the mid - late 1980's. Remember these decks.

These transformers often have a thermal fuse that is taped to the secondary which opens if the windings get too hot, or just from age. I have repaired a few transformers by replacing or bypassing this. I am glad the repair worked well. What I would personally do, remove the transformer from the adapter and solder it to the original place to keep it cleaner. Love your channel, keep it up

I think I have an identical unit in my basement and it still works great! My mom and dad were the original owners.

I miss Radio Shack. I mean the classic one that had good, basic versions of every day electronics, not the phone store.

Top tip on the turntable keeping it unplugged!

I still have on of these. I bought it a long time ago to digitize cassettes. (for a good while it sat on top of my PC's tower). Not a "feature packed" deck, but yeah, decent quality (especially compared to whatever crap is being spit out now!).

yeah that thing was duct taped in a janitor closet for a BGM in a store. so that thing burned out long ago.

I bought my SCT 86 in the mid-90s and it's still in regular use.

Excellent repair. Blown away by the sound quality of that cheap deck.

I had one of these from new. I bypassed the transformer and ran it off a pp9 battery. Added a Sinclair mini amp and small speakers and made my own boombox before they were ever a thing

I just picked up a similar unit for $4 at an estate sale!

I even remember going to RadioShack like it was the other day

great example of why sometimes thrifting is worth it. sometimes you pick up lemons that are too rotten but there are also times when you pick something up for a couple bucks and with some elbow grease it works like a charm. sounds nice for a deck that cheap.

I had an earlier version of this (Realistic branded).. Hooked up to their old stereo mixer.. Cheapy but workable dj setup

Having nothing to do on a rainy day but to look up old stuff and almost sorry I did.... So many positive comments !!! Son was starting out as a magician many years ago and needed some stuff. A cassette player , power amp & speakers. Thankfully the Shack was local. Performing shows every weekend ( @7 ) in October....Thankfully , kept my receipt , after the 3rd replaced cassette player - one replaced between shows and needing a 2nd power amp....Bye-bye Radio Shack......30 yrs later , still a magician !!!!!!!

That's actually a really nice form. I could totally have one on my desk connected to my computer speakers for my office.

The good old 80s pretty good tape deck 😎👍

Great advice about using a power strip with a power switch, no need to have the transformer permanently powered on, great video! Awesome little tape player, keep up the great videos coming 👍

I still have my early 2000 boombox with radio and CD and I enjoy it every time I can. Yesterday I visited a nearby recycling center and found a bag with 30 used audio tapes and 4 brand new sealed TDK. Also I found a old Sanyo from '79 I think, mono tape recorder with FM/AM/SW radio, a beauty. I still have to figure what is its fault because it powers up but no audio comes aside humming. It seems is made entirely with transistors, no ICs.

​@@imark7777777 It's simple. When you have an unregulated (non-stabilized) power supply, either AC or DC that is rated e.g. 12V/500mA, it means that - given the exact primary voltage - there's exactly 12 volts on the output when there's a current draw of exactly half an amp. On no or lower load, the output voltage will be higher; conversely, on higher loads, the voltage is brought down and the transformer saturates. And, of course, if the rating is in ac, it means 12 volts root mean square of the sine wave. When rectified (and filtered), the output voltage is the very amplitude of the sine, minus the drop of the rectifier.

@@JozefBogin that is amazingly the most simple explanation I've ever heard on the subject I finally get it. thanks!

Would I then be safe combining those two? Unfortunately only voltage and negative polarity are the things marked on the device so I'm going by eBay photos. I have yet to stick an amp meter on it as it was a few orders of magnitude larger than I was expecting.

This shows that there are different shades of BPC, and this one is perfectly usable, especially considering the price. Its S/N ratio is good enough for radio recordings, and its wow & flutter is surprisingly decent, although I wonder why you haven't disclosed the numbers you've measured.

This kind of transformer on the deck is fixable (they usually have a built in fuse/thermal fuse, only 110v transformers that have this fuse have 2 long pins that are soldered on the board and one short pin and all you have to do is measure to find what pins are soldered to the coils (generally one short pin and one long) i say that because i fixed a japanese boombox with the same problem and i added a external fuse to avoid burning the transformer

I liked the way they put together systems with all the components already matched to work together for different budgets. Remember the "Good, Better, Best"?

Unplugged or hooked up to a power strip for sure. 900 mW per channel with no balance control, separate right and left volume pots, which I prefer on the bench. Think it was $4.99 at the Goodwill.

good little rescue

I had the UK version of this tape deck (from Tandy) around 1990 - 95 when I used to host pub quizzes and did some occasional deejaying. (also had the Realistic battery operated Stereo Disco Mixer) It was useful if I had certain tracks on tape instead of vinyl as not being a full blown professional DJ then was sometimes cheaper to get tapes. It made finding a track on a tape interesting when trying to ffwd/rwd to find it while a record was playing so had approx 3 minutes before I would have to play. No-one seemed to notice the difference though. I was a bit upset when it eventually died on me. Well, the play button popped off and the soft(ish) eject nature of the door made it a bit slow for quickly changing tapes so I guess I was slightly too rough with it as it broke too but I think the final straw was when motor started to die too. Great wee device... 🙂

Had one of these for years on my speaker system round the house for years and it's been excellent. It seems to run to speed well with no noticable wow and flutter. Recently aquired the auto reverse version too, but I don't think Radio Shack here in the UK (Tandy) ever sold the recorder version.

Bought one of those for the family back in the day. Not sure what they would have done with it by now. I'm sure the owner taped this one down because you couldn't use it like a normal deck because it was too light. It either took two hands, or you'd have to hold down the top while reaching for the buttons on the bottom with the other hand. If you didn't do that, it would just slide around as you tried to push the buttons, lol.
