I wanted to see how you increase the gain :(

@deadman12078 I'm working on that; it looks possible. The electronics are based on a 2025 dual amplifier with a maximum gain of 46 dB. With the addition of a resistor, that gain is lowered. This circuit appears to have a 100 ohm resistor which brings the gain down to 36 dB. If I replaced it with something lower, say 47 ohms, it should get louder. Of course, one runs the risk of burning out the amp.

hope you found your glasses!!

@bearpatch626 Yes! I found them. I don't know why she finds them so interesting.

Loved the co-host at the end there! Thanks for the video!

@srhenderson186 LOL! She has to touch everything! If I leave her alone for a while, she will start cutting my solder into 1 inch lengths. :-)

It is quite common that screws are hidden under speaker grills.

LOL...we have all been there...trying to figure out how the widget was designed/assembled. Guess I would have cut an inspection hatch on the backside near the top to get a view inside. I just disassembled an old flat-plate scanner...amazing where they hide the hardware! Good luck and thanks for the dissection!

Nice video .. thanks.

@wtam69 Each side has a 3 Watt, 4-ohm speaker with some good sized ferrite (?) magnets. The system is advertised as 5 Watts so I suppose it puts out 2.5 Watts per channel. These were on sale at Best Buy. I was just taking a chance that they would work with the piano output so I didn't want to spend a lot. Wouldn't you know it, I threw out all the speakers that came with my computers over the years. I usually break things too. I thought a video might help someone else. :-)
