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.

So far I have modified several aspects of the Sure TA2024 board. In this article I look again at the input to the device and swap over the input capacitor.

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 in another article, I showed how the Sure Tripath Boards unacceptable DC could be reduced significantly by removing a pair of resistors from the PCB effectively disabling Sure's attempt at a DC offset reducing circuit.  This article takes the modification a step further to eliminate DC offset completely.

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?

Already on www.justblair.co.uk we have looked extensively at a brilliant amplifier from Sure Electronics.  The Tripath TA2024 board is a cost effective, high quality amplifier board that in stock form offers value and with a few tweaks can offer serious performance.  It was with great interest that I awaited a sample of the recently released “Big Brother” to this amplifier… The Sure 2*100 watt @ 4ohm TK2050 Class-D Audio Amplifier Board (product code: AA-AB013). Well it’s here in my grubby mitts and today I managed to find some time to give it an initial listen.

Available for $39.99 excluding delivery, this board is a pocket money buy, question is can it deliver decent performance at this measly price?

I bought the Sure Tripath amps a while ago.  I have intentions of modding them to improve the sound and then using them as part of my next amplifier project.  This weekend I started playing with them.  you can look at my mini review of the product here

 Expect a review and an article or two detailing how to mod them in the next few days.

I have 5 of the stereo amps, which will  give me 10 channels for the next amp.  Thats a channel for every driver on my Mission 753 speakers.  I intend actively filtering the whole setup for maximum amplifier damping.

These Sure amps are incredibly cheap at $22 each!
