Tiny clear acrylic computer speakers from Amazon.

Recommended Posts

These are marketed on Amazon as a project suitable for young novice hobbyists.  IMO, this is NOT suitable for beginners.

 

I purchased these to provide better sound from the small TV in our kitchen.   The TV’s small single speaker recently developed an annoying buzz.  The completed acrylic speakers sound better than the original speaker ever did.

 

I have assembled two Heathkit color TVs, numerous Dynaco kit amps, and many DIY amps.   The instructions provided were inadequate.  After searching Google for instructions, the instruction deficiency was mitigated.  In addition to the lame instructions, it is necessary to surface mount a tiny IC chip amp to the PCB in each speaker.  Eight tiny attachment points need to be soldered for each IC.

 

Some parts we’re not labeled. Without any explanation, extra resistors were supplied.  If having parts left over makes you uncomfortable, avoid this kit.

It looks like an 8 pin SIP. When I was a teenage party animal, I was unsoldering and soldering in new op amps when my Pioneer Supertuner under dash stereo blew them out. Today the young novice hobbyists don't have Radio Shack kits to solder together, or even know who Alfred P. Morgan was. I have a whole collection of his books, purged from libraries around the country. The instructions for the last kit I put together (a 4 tube AM superhet) were printed in Japanese, an enjoyable challenge, but it worked.

How many of you have a coffee cup (or some ‘round’ container) stuffed with writing instruments on your kitchen counter? I do..........  🤓

Now that they’re working, they’re behind the TV firing up.  I’ve ordered stuff needed to hide the wires behind the TV.  My wife doesn’t want to see the speakers or any evidence of the speakers.
