Trash To Treasure! A SONY Cassette Recorder Adventure.

This video is all about the benefit gained when I picked up a fine quality business machine that was thrown away by a careless business which abused and did not appreciate it.
SONY built (and continues to do so) excellent cassette recorder solutions for different markets. The SONY BM-11 was built as a dictation machine, but it is actually a high quality cassette recorder, probably built in the 1980's "Walkman Era". It uses standard cassettes, features "SONY-MATIC" recording, AC Bias, FOUR belts and SOLID BRASS drive components. Most of the machine is made of metal, minimizing the use of plastic. Although designed primarily for dictation, it can record and playback music (in mono, of course).
This video shows the high quality SONY dictation machine in operation - playing music - a selection from the "Symphonia Felina" neoclassical music album, and accepting dictation through both it's built in electret condenser microphone and an external microphone.
I found this machine in the trash, tossed away because battery corrosion destroyed a vital power contact on the machine, making it inoperable. It also had a stretched main drive belt which I replaced, and a dead amplifier which I "revitalized" when I restored this machine - a broken wire and "cold" solder joint was all that needed help. Although the inside of the machine is tightly packed with components, they are remarkably high quality and capable of much longer service than the business that tossed it away realized. Perhaps it was too expensive for them to have it repaired when the trouble first started? The condition of the leather case shows it did receive a lot of use, probably by traveling executives.
The mechanism is entirely unique, having a DOUBLE flywheel arrangement to assist the capstan in maintaining constant speed!
While a dictation machine is a specialty business product (often more expensive than a general consumer product), as the SONY BM-11 proves, it is not necessarily limited to dictation. This machine is an example of how SONY "thought outside the box" and used clever innovative engineering to make a high quality cassette tape recorder suitable for a variety of purposes, from dictation to music recording and playback.

I like both SONY and AIWA products. But I like to make jokes that AIWA is better, because in fact, SONY is better. The two competed strongly in the market in the 1960's. Think MAC vs PC. BOTH are good, for different reasons.

hey clydesight,i though you don't like sony prouducts. do you like sony or awia?

@MetallicBill The Web has plenty of suggestions for cleaning battery corrosion (vinegar, baking soda, etc). I find the only real solution is to sand and scrape the surface of the corroded parts to get down to raw metal once more - if that is possible.
MetallicBill(5 months ago)
@clydesight The first Walkman was only 1978 or 79. Can't be TOO old. The cost of a belt replacement, or speaker I can see, but the audio amp BOARD is not worth it ultimately. My 310 recorder had corrosion battery terminals VERY similar, I soaked it in water and used a toothbrush on it for some time and it's still iffy! They can get VERY fouled up, soda pop might work better for cleaning metal

I'm not sure, maybe he didnt have it secured right like teetering on the edge. I really dont know b/c I was downstairs when it all happened. All I remember is hearing a loud bang and then what the heck was that? being said. it could have been ghosts, maybe I should get the T.A.P.S team Jason and Grant from ghost hunters up there to investigate LOL. I love that show.

@coondogtheman1234
Oh, that;s too bad. How did the computer monitor fall on it? Ghosts maybe?
coondogtheman1234(6 months ago)
It wasnt dropped. the person who owned it before me had it in the wrong place and I think a computer monitor or something fell on it and that broke the screen. All I remember was sitting in my friend's kitchen doing something and I heard a loud crash and my friend went upstairs to see whats going on and his room was a mess. the PSP was on the floor screen smashed. that's how I got it, he gave it to me b/c it was destroyed but I saved it.

@coondogtheman1234
Too bad it was dropped!
I agree, much of the old technology can be fixed, but this modern tiny stuff is not only hard to actually use, fixing it is impossible.
Which means that 40 years from now, it won't be around, not like the old radios and tape recorders from the 1960's. Pity, so much innovation, but only for its own sake. What happens to permanence and consistency in such a world?

@clydesight
My PSP wasnt dropped it was owned by someone else and something fell on it and it was brand new. I just fixed it. but you're right when one tiny part fails the whole thing is garbage. thats what i hate about surface mount parts they are so freaking tiny yet not as reliable as old technology. at least with old technology you can fix it.
clydesight(6 months ago)
Oh, too bad.
Specialized technology has the problem of being special. If it fails and they drop it, what can you do? Sony should have more sense.
I have a vid on the pico cassette recorder, another "dead" technology that never took off. Tiniest cassette ever made, the size of an airmail postage stamp. Just search pico cassette and my vid will appear.

@clydesight
its not a CD based drive its a special format of disc. I will probably just either get a new UMD drive or a new PSP.

@coondogtheman1234
I don't know anything about SONY PSP stuff but if it's a CD drive, can you maybe put in a replacement? There are surplus electronics places all over the Internet, you might find something inexpensive that works!
coondogtheman1234(6 months ago)
I's a shame that people will throw away stuff like this. I love it when I find electronic stuff in the trash. it just feels so good knowing that, A, I can keep it and, B, its not going into a landfill and polluting the environment. My sony PSP handheld video game was trash to treasure all it needed was a new LCD screen and some TLC and its functional but i cant play games b/c the Drive where you put the game doesnt work.

@Ziplock74
Thanks. I don't know the history on this thing as it was found in the trash.
I found this years ago (around 1982) and it probably was around for some time, so it might date from the mid-to-late 1970's.
Small cassette dictation machines came out in the 1960's and progressed from there. See my video:
Big Little Tape Recorder - Magnavox 1v9019
for an example of a 1960's early dictation unit -- and a pretty good one at that!
Ziplock74(6 months ago)
cool video, great find! the bm-11 is the earliest predecessor to the sony walkman. i can't find an exact date for it but it's most likely a late 60s/early 70s item.

I assume that was a compliment, if so, thank you!

Damm you know your shit

It does require a special battery holder (that was inside the machine when I found it), and I imagine there was a rechargeable battery pack for it. It can run on any AA battery, alkaline or otherwise.
Lachlant1984(1 year ago)
Does the unit use some sort of special rechargeable battery pack? It looks like it does. If so, can you use the unit on standard Alkaline batteries? Oh how I hate battery corrision.
CassetteMaster(1 year ago)
By the way, what did you do to fix this one's amp?
clydesight(1 year ago)
E-Bay is so strange, I just got a Grundig Embassy Mark V (dictation) when no one bid against me. Then I got sniped on a Miranda Nocturne. Sigh. I am glad my video inspired you with your BM-11 and that it is a useful machine for you. Thanks for letting me know something I posted here had value!
