PSU for TA2020 mk3

studiostevus · 15th November 2009, 08:42 PM

Guys,
I recently ordered one of Arjen Helder's ta2020 mk3 boards of ebay.

As this will be my first project, it's a fully populated board, I just need to arrange a PSU and casing.

Does anybody have experience with a good solution to provide the amp with 9-15V? I'm looking for the best value for money solution (good quality, not too expensive).

Thanks!

Hi studiostevus, cheapest way (and perfect working) is a switching power supply. You can order them from Arjen or Sure Electronics on Ebay. You can also find them in the Netherlands. I ordered mine from DIL in Rotterdam.

I have a TA2020 from Arjen and use a Samsung 14v 4A Supply for a Monitor. It works Great. The only trick is that you have to change the Tip because it comes with a Center Pin.

I was actually planning to use a built-in psu, not sure if using an external one has any impacts...

by the way, Arjen's datasheet tells me it needs 3.5A peak

indeed peak, the psu that is rated at 3 amps continuous is more than enough, in normal use this little amp will not use more than 1 ampere

Please do not be surprised if the TA2020 goes up in smoke one day. 14 V is too close to the absolute max. of 14,6 V. TA2020 is sensitive to overvoltage and the power supply probably gives more than 14 V too. A dangerous combination for your speakers.

By the way, is there anyone who has some pics of a nicely implemented Arjen Helder amp?

Looking for nice casing, but since the board is 5cm high, Eurocard cases are out...
