The Sure Electronics Tripath TA2024 Board is out of the box a good value for money amplifier module. However with some careful tweaking it can be made to sound better. This article focuses on the power supply to the Tripath chip and shows some improvements that can be made.

Mine has clearly seen a hard life, now aged, yellowed and partly functioning. This is the first instalment in its journey back to greatness. While I doubt many of you will be refurbishing one of these, along the way we should see some of the circuits required to build your own workstation.
Not only that, as impressed as I was by the hacks that have been done already on digital callipers, the execution has been pretty ghetto looking. I had an idea that would produce a more stock looking finish that I think is more durable.
I have already investigated improving the cooling on the Joggler and replaced the standard cooling system with something more substantial. I have also been using and improving the Squeezeplay software ported over by Tarkan. All in all my Joggler is providing excellent value as a touchscreen media player on my headphone rig… But I had a niggle or two left to solve… Here is the problem, a standard Joggler has one side mounted USB port, and that is awkward and limiting in equal measure. Time for change!
For those that choose to run other operating systems on the Joggler, this can be frustrating. Start using anything like processor intensive tasks with the diminutive tablet and quickly you will push it beyond it’s thermal limits. I tried it out for myself using CPU burn and within a minute or two the processor maxed out. The processor then went into a lower performance mode to protect itself Lets have a look at the Joggler’s cooling hardware and see what can be done to improve it. |
The Sure Electronics TA2024 Amplifier impressed on my first inspection although suffered from Poor DC offset and a slightly dull sound. This is the second modification I have made which is aimed at improving the top end sound of the amp.
In the last article we looked at the Sure TA2024 amplifier boards, fresh from their box. Amongst the issues identified is that the Sure boards have an issue with DC offset. This article shows how with a very quick modification the DC offset of the boards can be improved upon.
The Sure Tripath amplifiers offer a Tripath 2024 chip Class T amplifier for $22 plus shipping from Najing, Jiangsu, China. So what do you get for roughly £15 of amp?
