I've read all sorts of opinions about boombox acoustics and class D amps. Not that many actual implementations. So I decided I would find out for myself...
The "iPod Viking" is a perfect candidate for a power vs. size ratio update. Definately, there's room for enhancement.
I gathered a few parts...
This is work in progess but pretty much done as this point. Here's the back cover...
I've replaced the transformer with a more capable SMPS
I've used the transformer posts to mount a step-up converter that bumps up the voltage going the amplifier. The amp can use from 9 to 24 volts. Theoritically it should work at full power (24 volts) using D batteries. For how long remains to be seen. Not a big concern...
The relay in the bottom is the amp power switch
And the amp itself. It is a T1-M from HiFimeDIY. There's no precise spec for its output power but if set to the highest voltage it should likely push around 25 WRMS into each channel.
At this point I still need to work on the front part. I'll be back with more pictues.. Stay tuned !
