Tripath DIY Audio MK11 TA2020 PCB Fully finished and tested
Excellent Audiophile Quality  amplifiers are very expensive....  or are  they?
This Amplifier board is of Excellent Quality and sounds very good on any pair  of loudspeakers.
MKll Tripath  TA2020 PCB 25watt Class-T amplifier   Version !!!!!!!!!

We  will have our own brand fully finished  amplifier with housing soon with all our  PCBS also Valve pre-amplifier, please have  a look at our newest version MKlll version  TA2020 pcb and TA2024 PCB.

Improvements to the PCB:


-400 volts  2.2uF audio grade film capacitors! and  plenty of space for upgrades!
-Connectors  all situated at once side for eazy  installation
-Bigger  board size for more space to replace  components
-Bigger  output coils with a better transient  response and thicker copper wire.

Make your own amplifier, this is  an excellent way to start!  This PCB needs  12 volts at 3 ampere minimal to function  properly and is therefore safe to use for  anyone as 12 volts is a low and safe  voltage.  
The sound quality from this board  will amaze you with great clarity, detail  and clean and tight bass response. 
Online discussions about  this amplifier can be found on DIYaudio  forum ,ArjenShenzhen  , or simply google DIYaudio and  TA2020 and you can find scores of  information to get you going, and friendly  fellow DIY'ers to help you along!!
